Frequently asked questions

What does 'Shore Hardness' mean?

The Technical Answer:Shore Hardness scales are used to measure the hardness or density of a material. These scales were invented so that people can discuss these materials and compare them using a common unit of measurement.

The Shore A00 Scale measures rubbers and gels that are very soft.

The Shore A Hardness Scale can be used to measure the flexibility of rubbers ranging from very soft and pliable to very stiff with almost no flexibility. Even Smooth-On’s semi-rigid plastics can be measured on the high end of the Shore A scale.

Shore D Hardness Scale measures the hardness of hard rubbers, semi-rigid plastics and hard plastics.

 How Do You Physically Measure A Material’s Hardness?

The different Shore Hardness scales measure a material’s ability to resist pressure.. A ‘Shore Hardness’ gauge (looks like a round tire pressure gauge) has a needle on a spring protruding from one end. The needle is placed against the rubber or plastic and pressure is applied.

Once the gauge is pressed firmly against the material and the needle has penetrated as far as it can go, the measurement needle will show where the material falls on the Shore Hardness scale.

What Shore Hardness means to you as a mould maker:

Smooth-On manufactures many different varieties of mould rubbers and castings resins. Some types of rubber work best for certain applications.

When choosing your Smooth-On moulding rubber, there are some factors to take into consideration. The main factor to consider is how easily your casting will be released from the mould.

For instance, figurines with thin limbs will snap if cast in a mould with little give. A better choice would be a Shore 30A rubber or softer that would offer enough flexibility to easily extract the model.

Stiffer rubbers are better for casting clean geometric shapes (such as blocks or paving stones), as well as castings made of rough material like concrete. This will minimize the chance of the casting warping. In this case you should choose a 70A rubber for your project.

What is the easiest way to wash my Smooth-On materials off my skin and work space?

Smooth-On does not recommend allowing moulding and casting products coming in direct contact with unprotected skin. The exception to this rule are our silicone and alginate products which are expressly made for applying directly to the skin.

If contact with skin does occur, it is best to clean the material off while it is still in it’s liquid state. Using a soft cloth, lightly wipe clean with Acetone or Mineral Spirits and then wash affected area with soap and water.

Removing Material from Tabletops and Other Surfaces

Smooth-On’s urethane rubber or plastic will bond with most surfacing during the curing process, which makes them extremely difficult to remove. Your best bet is to clean up spills while material is still in a liquid or gel state. Once cured, material is very hard to remove.

Silicone Rubber does not stick to many surfaces. In most cases, you can simply allow the silicone to cure, and then peel it off when dry. However, silicone will mechanically lock onto many porous surfaces (concrete, for example). Silicone will also stick to glass. In these cases, it is best to remove rubber while it is still liquid.

Smooth-On Castable Epoxies and Epoxy Adhesives are adhesive and will bond to most surfaces. Once dry they are difficult to remove without causing damage to the surface, so it is best to remove these while still in a liquid state.

As a general rule, once cured, most materials are difficult to remove.

What To Use For Clean Up:

General purpose solvents such as Acetone, Mineral Spirits (Paint Thinner), Toluene and Xylene are usually effective. They are commonly available at Hardware and DIY stores. Important: Follow all safety precautions found on container when handling these and other solvents.

What effect does temperature have on the mould making and casting processes?

Smooth-On moulding and casting materials can be affected by temperature and humidity. How a material is affected depends on the specific chemistry of the product.

Latex mould making rubber, latex foam and acrylic latex polymer products (such as Matrix G, C and Neo).

For best results, store and use latex products at room temperature (72°F / 23°C). Important: if latex is allowed to freeze, the contents will separate and become unstable. This product will no longer be useable.

Cold – Any material containing latex is affected by cold temperatures. Being in a cold environment, especially with high humidity, will stall the evaporation process, and the latex will take longer to dry.

Heat – higher temperatures will cause Smooth-On products containing latex to cure faster. Making a latex based mould in hot weather and low humidity will cause your mould to set much faster. Keep this in mind while making your latex mould.

Humidity – humid environments will slow the evaporation process thereby slowing the cure of latex rubber.

Urethane Rubbers, Plastics and Foams

For best results, store and use Smooth-On urethane products at room temperature (72°F / 23°C). If the product freezes, it can only be used again if it is allowed to come back to room temperature first. Thoroughly pre-mix Parts A & B before dispensing and mixing.

Cold – Colder temperatures will increase working time (pot life) and delay cure time of urethane rubbers and plastics. If urethane rubber or urethane plastics that take overnight to cure are applied in too cold of temperatures, they may not cure at all.

Heat – Elevated temperatures will reduce the pot life and cure time of urethane rubbers and plastics.

Humidity – Urethanes are easily affected and should be used in a low humidity environment. Humidity will react with urethanes and may cause bubbles or foaming in the material. See Smooth-On’s FAQ on factors affecting moulding and casting materials.

Silicone Rubber

For best results, store and use Smooth-On’s silicone products at room temperature (72°F / 23°C). If material freezes, silicone base will become very thick. It can be used after being brought back to room temperature. Mix parts A and B in their containers thoroughly before dispensing and mixing.

Important: storing silicone in higher temperatures can reduce the shelf life of your silicone mould rubber.

Cold – Tin-Cure Silicones – Colder temperatures do not have as dramatic an effect as they do on other materials. Some of Smooth-On’s rubbers have accelerated pot life. These can be used to make moulds over frozen models.

Platinum-Cure Silicones – Colder environmental temperatures will increase working time (pot life) and delay cure time of platinum silicones. If used in an environment which is too cold the silicone may not cure at all.

Heat – Tin-Cure Silicones – warmer temperatures do not have as dramatic an effect as they do on other materials. You cannot “heat cure” tin-catalyzed silicones.

Platinum-Cure Silicones – Elevated temperatures will reduce the pot life and cure time of platinum catalyzed silicone rubber. You can even use this effect to your advantage. Many mould makers will use heat to accelerate the cure time (demould) of platinum silicone moulds.

Humidity – Tin-Cure Silicones – Will cure faster in humid environments.

Platinum-Cure Silicones – Humidity generally does not affect platinum silicones.

In addition to environmental temperatures, you need to monitor:

1. Temperature of material in containers – The temperature of the material NOT the temperature of your work space determines how the material is effected. For example, even if your workspace is room temperature, your urethane plastic will still have a shorter pot life if it was previously stored in a hot garage. Always be mindful of where you store your Smooth-On containers.

2. Temperature of original model or mould – Mold Making – if the model to which you are applying rubber is too cold, mould rubber will take longer to cure or may not cure at all. Make sure your original model is exposed to at least room temperature several days before applying mould rubber. What If My Model Is Frozen? There are applications calling for making a mould over a frozen model. For this purpose, Smooth-On has a line of accelerated silicone rubber (such as Mold Max 30 with Fast Cat curative). The model will begin to condense as soon as it is exposed to warm temperatures, and the moisture coming off of the model will not affect accelerated silicone.

Casting – if you are casting a fast cure urethane plastic that has a high exotherm into a cold mould, you may experience what is known as “thermal shock”. Thermal shock may cause surface imperfections in the casting.

What does the term "shelf life” mean?

All Smooth-On products have a pre-determined life. Shelf life refers to how long a product can sit in a container on the shelf before it will not longer function normally during use. Always keep in mind how long your material will last, and plan accordingly.

Factors such as temperature and humidity can shorten the shelf life of Smooth-On rubbers, plastics, foams, Matrix products, epoxies, etc.

Shelf Life – Urethane Rubber, Plastic or Foam In Unopened Containers

Smooth-On urethane rubber, plastics and foams should always be stored in a room at room temperature (73°F/ 23°C). When stored properly, these products will last 1 year from the date of manufacturing in an unopened container.

Shelf Life – Urethanes After Containers Have Been Opened

The shelf life of unused product in containers that have been opened depends on exposure to ambient moisture in the air. The Part A side (yellow container) can be negatively affected by moisture. When mixed with Part B, moisture contamination may cause bubbles in the final casting. See Smooth-On’s FAQ on bubbles in castings for further details.

Urethane Rubber – Unused Part A product exposed to humidity will begin to turn from liquid to solid in as little as a few hours. Part A exposed to relatively low levels of humidity will last two to three months in the container before showing signs of moisture contamination.

Limited Shelf Life Of Urethanes – What Can You Do?

Make sure you securely seal the Part A container immediately after dispensing each time. This will shorten the amount of time it is exposed to ambient moisture in the air.

Your Best Bet – If using urethanes, use what remains as soon as possible once containers have been opened. We recommend buying in smaller quantities if the remaining material will not be used for an extended period of time.

Extending The Shelf Life Of Unused Urethanes – After dispensing Part A into a measuring container, spray XTEND-IT Dry Gas Blanket (available from Smooth-On or your Smooth-On distributor) into the container before securely resealing.

XTEND-IT will effectively double the shelf life of the remaining product by neutralizing the moisture filled air in the container. See instructions before using.

If you are working in an industrial or production environment, a nitrogen cylinder may also be an option. They are sold in large cylinders, and will remove ambient moisture from the air.

Shelf Life -Silicone Rubber

Properly stored at room temperature (73°F/ 23°C), Smooth-On’s silicone rubber will have a shelf life of 6 months from date of manufacture. The manufacture date can be determined by the lot number that can be found on the label of Part A or Part B. You can contact Smooth-On with these numbers to determine when the product was made.

Important – Elevated temperatures will drastically reduce the shelf life of silicone rubber. For example, silicone rubber stored at 80°F / 27°C will have a shelf life of about six months. Material stored at 100°F / 38°C will have a shelf life of about two months.

Shelf Life – Polymer Modifiers for Gypsum & Concrete

DuoMatix G, C and Matrix NEO – Properly stored at room temperature (73°F/ 23°C), Matrix products will have a shelf life of 1 year from date of manufacture. The lot number can be found on the latex component of the Matrix You can contact Smooth-On with these numbers to determine when the product was made.

Important – The latex component of DuoMatix G, C and Matrix NEO must not be allowed to freeze in the container. The latex component of the Matrix products must not be exposed to temperatures below 35°F / 1.7°C.

Shelf Life – Rubber / Plastic Accelerators, SO-Strong Color Tints, Silc Pig Color Pigments and other accessories – at least 1 year from date of manufacture.

Shelf Life – Epoxy Adhesives – One year from date of manufacture.

Shelf Life – Powder Fillers – at least 1 year from date of manufacture.

Important: Keep powder fillers dry.

When Was A Material Manufactured? After locating the lot number on the label of Part A or Part B. You can contact Smooth-On with these lot numbers to determine when the product was made.

Definitions of Technical Terms You May Encounter

Compression Set – Measures the resistance of material to permanent deformation. In this test, a rubber pellet is squashed to 75% of its original height, kept at that deformation for 22 hours. It is then released and allowed to return to its original height. The value reported is the percentage not returned to the original height. The smaller the number the better.

Compressive Strength – Measures the force, in PSI, needed to crush a material. A compressive modulus, which measures the resistance to being crushed, is also determined. The compressive modulus is only measured for rigid materials.

Curing Agent – A catalytic or reactive agent which when added to a resin causes polymerization; synonymous with hardener.

Curing Temperature – Temperature at which a cast, moulded, or extruded product, a resin-impregnated reinforcement, an adhesive, etc., is subjected to curing.

Curing Time – The period of time for a material to fully cure. Also called demould time.

Deflection Temperature Under Load – The temperature at which a simple beam of material has deflected a given amount under load. Also called heat distortion temperature.

Delaminate / Delamination – To split a laminated rubber or resin material along the plane of its layers. The physical separation or loss of bond between laminate piles.

Flash – Extra plastic attached to a moulding along the parting line.

Flexural Modulus – The ratio, within the elastic limit, of the applied stress on a test piece in flexure to the corresponding strain in the outermost fibers of the piece. Only measured for rigid pieces.

Flexural Strength – Measures the force, in PSI, needed to bend a material until it breaks. A flexural modulus can also be determined which measures the stiffness when bending the material. With plastics this value is usually higher than the straight tensile strength.

Flow – The movement of resin under pressure to fill all parts of a mould.

F.R.P. – Fibrous-glass-reinforced plastic; any type of plastic reinforced cloth, mat, strands, or any other form of fibrous glass.

Gel – The initial semisolid phase that develops during the formation of a resin from a liquid.

Gel Time – The point in time after introducing a catalyst into a liquid polymeric system until the material becomes a continuous mass. Note: For some Smooth-On rigid urethanes, the Pot Life and Gel Time are almost simultaneous, whereas, for the elastomers there is a considerable amount of time between the end of the Pot Life and Gel Time. Also working time and gel point.

Gel Coat – A resin applied to the surface of a mould and allowed to gel prior to laying up subsequent layers. Usually used to improve the surface appearance and protect the underlying laminate from the environment.

Guide Pin – A pin or key used to bring mould halves or sections into alignment on closing or joining together so they will not shift. Usually consists of a depression in one part and a matching protrusion in another part.

Hand Lay-up – The process of placing and working successive layers of reinforcing material or resin-impregnated reinforcement in position on a mould by hand.

Hardener – A substance added to the plastic composition to control the degree of hardness of the cured plastic.

Hardness – Shore A Durometer; Shore D Durometer; Barcol 935 Impressor. Hardness measures the resistance of a material to indentation. The three hardness measuring devices used by Smooth-On are basically made of a needle on a spring that measures how far the needle indents the material. The Shore A device is a dull needle on a weak spring for measuring elastomers. The Shore D device is a sharper needle on a stronger spring for measuring rigid materials. The Barcol 935 device is an even sharper needle on an even stronger spring for measuring very hard materials. These devices are excellent for determining if a cast material is curing properly.

Most people use durometer measures as the first criteria for determining the material they need by stating, “I want a Shore A-40 rubber that will…”. The hardness gives an indication of the type of properties to expect from a material but is not always the best indicator of performance.

Heat Distortion Temperature – Measures the temperature at which a rigid material becomes rubbery. A cast bar of material is placed in an oil bath and a flexural load is applied. The oil is heated until the bar bends a preset amount.

Impact Strength – Ability of a material to withstand shock loading.

Inhibition – The failure of a material to cure properly.

Injection Molding – Liquid resin that is forced into a mould while under pressure. This will enhance the quality of parts by eliminating air bubbles.

Laminate – To unite sheets or layers of material such as rubber or fiberglass by a bonding material. Pressure and/or heat may also be involved.

Lay-Up – As used in reinforcing; process of brushing or hand laying material into a mould.

Life Mask – A mould made of a living person’s face or head. This is accomplished using with Alja Safe alginate or Body Double silicone rubber.

Load-Deflection Curve – A curve in which the increasing flexural loads are plotted on the ordinate axis and the deflections caused by those loads are plotted on the abscissa axis.

Master Model – An exact duplicate of a model, used to make numerous moulds. Saves the actual model from the damage during mouldmaking.

Mat – A fibrous material for reinforced plastic or gypsum consisting of randomly chopped filaments or swirled filaments; available in blankets of various widths, weights, and lengths.

Micron – One micron = .001 millimeter = .00003937 inch.

Mix Ratio – Expresses the proper proportion (either by weight or volume) of Parts A and B to be combined before pouring or brushing on model. By weight requires the use of an accurate scale whereas by volume requires only the use of equal size measuring containers.

Model – Your original object or pattern. Models can be anything made of wood, plastic, wax, clay, metal, plaster, bone, rock, etc. A model can be any shape, pattern, or texture you want to reproduce.

Modulus – Key physical property that indicates hardness of a material. More specifically, the modulus is the amount of force needed to deform a material a set amount. Modulus is measured in PSI and can be measured in any mode of deformation, i.e. tension (stretching), compression (crushing, flexing (bending), or torsion (twisting).

Modulus Of Elasticity – The ratio of the stress or load applied to the strain or deformation produced in a material that is elastically deformed. If a tensile strength of 2000 pounds per square inch results in an elongation of one percent, the modulus of elasticity is 2000 divided by 0.01, or 200,000 pounds per square inch (Young’s modulus).

Mold – The cavity / form that carries a negative or reverse impression of an original model. Molds can be made of a rigid material, such as plaster or plastic resin or more commonly, a flexible material such as rubber. The material to use should be chosen considering the material of the model, the material to be used to make castings, and whether there are any undercuts.

Mold-Release Agent – A spray, liquid or powder used to prevent sticking of moulded articles in the cavity.

Mold Shrinkage – The immediate shrinkage which a casting undergoes when it is removed from a mould and cooled to room temperature; the difference in dimensions, expressed in inches per inch between a moulding and the mould cavity in which it was moulded (at normal temperature measurement); the incremental difference between the dimensions of the moulding and the mould from which it was made, expressed as a percentage of the dimensions of the mould.

SDS – Also Safety Data Sheet; listing all hazards associated with the material and all safety precautions that should be taken when working with the material listed on the sheet.

Multiple-Cavity Mold – A mould with two or more mould impressions; that is, a mould which produces more than one casting per casting cycle.

Parting Line – A mark on a moulded piece where the sections of a multi-piece mould have met in closing.

Pinhole – A tiny hole in the surface of a plastic material; usually occurs in multiples.

Pit – A small crater in the surface of a plastic.

Plaster – A white powder consisting mostly of gypsum. You mix plaster powder with water to make a thick liquid. You can then pour the liquid plaster into a mould to make a cast product. The plaster cures to make a rigid white casting.

Plastic Tooling – Tools constructed of plastics.

PLI – Pounds per linear inch.

PSI – Pounds per square inch.

Post-Cure – Additional elevated temperature cure, usually without pressure, to improve final properties and/or complete the cure. In certain resins, complete cure and ultimate mechanical properties are attained only by exposure of the cured resin to higher temperatures than those of curing.

Pot Life – The amount of time that a catalyzed material remains workable (pourable for a liquid or trowelable for paste) after components have been mixed together.

Premix – A moulding compound prepared prior to and apart from the moulding operation.

Pressure Pot – A chamber used to compress any entrapped air bubbles out of casting.

Reinforcement – A strong inert material such as glass fibers, cotton, or burlap that is added into a casting material to increase the strength of the finished product. Some casting materials act mainly as binders for reinforcement. It is the reinforcement that gives strength, hardness, and break resistance.

Release Agent – A material applied in a thin film to the surface of either an original model prior to applying mould rubber, or the mould surface prior to casting. Release agents prevent adhesion between two materials that would stick together.

Resin – A solid or semisolid material usually having a softening or melting range.

Room Temperature Curing – Materials set to handling strength at temperatures from 68° to 86° F and later reach full strength without heating.

Room Temperature Vulcanization – RTV: Certain rubbers need heat treatment to cure, or vulcanize. RTV rubbers cure with no special treatment.

Rotational Cast – Referred to as spin-casting or slush-casting; rotational casting is the process where a small amount of casting material is poured into a mould. The mould is then either rotationally spun by hand or machine to coat the entire surface of the mould. This process is continued until the casting material has begun to gel leaving a hollow cavity that may be filled with a lower cost material.

Sealing Agent – A material that is used to coat your original model so that the rubber mould does not adhere to it. Models that are porous (wood, concrete, etc.) or those that contain sulfur or water need to be sealed. A suitable sealing agent may be obtained from Mann Formulated Products. Sometimes shellac or PVA may be used.

Set-Up – To harden, as in curing.

Shelf Life – The period of time during which a liquid rubber or liquid plastic can be stored under specified temperature conditions and remain suitable for use.

Shrinkage – The relative change in dimension between the length measured on the mould when it is cold and the length on the moulded object 24 hours after it has been taken out of the mould. A difficult value to predict since it is dependent on many factors. A few factors include the size and shape of the casting, the type of mould material and the ambient temperature. The test allows a comparison between materials to determine which would have the least shrinkage. Measured in inches per inch.

Shore Hardness – see Hardness.

Split Mold – A mould in which the cavity is formed of two or more components held together by an outer chase. The components are known as splits.

Spray-Up – Techniques in which a spray gun is used as the processing tool. In liquid rubber, two equal parts of rubber are fed through a meter-mixing machine that then sprays the mixed material against the model to be moulded. In reinforced plastics fibrous glass and resin can be simultaneously sprayed in a mould. In foamed plastics, very fast reacting urethane foams or epoxy foams are fed in liquid streams to the gun and sprayed on the surface. On contact, the liquid starts to foam.

Sprue – A funnel-shaped opening in a mould where you pour a casting material into the mould. Also, the waste casting material in opening of a mould after you make a cast product.

Specific Gravity – The ratio of the weight on any volume of a substance to the weight of an equal volume of another substance taken as standard at a constant or stated temperature. Weight measurement expressed in grams per cubic centimeter.

Tear Property – Indicates the materials resistance to tearing and is measured in PLI. There are different methods for testing a materials tear property. The test procedure Smooth-On uses involves cutting a 90º angle in the material then stretching the material until it tears. Another method involves preparing a sample of the material in the shape of a pair of pants then pulling the legs in opposite directions until the material tears. Each method will give vastly different values for the same material.

Tensile Properties – Include Ultimate Tensile Strength, Elongation at Break and 100% Modulus.

Ultimate Tensile Strength is the force, measured in PSI, needed to stretch a material until it breaks.

Elongation at Break is the amount the material stretches before it breaks. Elongation is measured as a percentage of the materials original dimensions.

100% Modulus is the force, measured in PSI, needed to stretch the material to twice its original dimensions.

Tensile Shear Strength – Measures a materials adhesive strength by determining the force needed to pull two pieces of metal apart that have been bonded together.

Undercut – Any indentation or protrusion in a shape that will prevent its withdrawal from a one-piece mould.

Viscosity – The resistance of the material flow measured in Centipoise (CPS). A material with a low viscosity will flow easily. The viscosity of water is 1 CPS. A material with a high viscosity will not flow easily. The viscosity of peanut butter is roughly 250,000 CPS. In relation to viscosity the following terms apply:

Shear Rate – Measures how vigorously a material is being mixed. Low-Shear Rate is gentle mixing. High-Shear Rate is very vigorous mixing. Note: In Newtonian Flow, the viscosity stays the same regardless of what Shear Rate is applied.

Psuedoplastic Flow – Viscosity decreases as the Shear Rate increases making the material flow more easily the harder it is mixed.

Thixotropic Flow – Very similar to psuedoplastic flow in that the viscosity decreases as the Shear Rate increases, however, when the mixing stops thixotropic materials do not immediately return to their original viscosity. Thixotropic materials build viscosity slowly over time.

Dilatant Flow – The viscosity increases as shear rate increases causing the material to appear thicker as it is mixed.

Does Smooth-On offer food safe moulding products? Can any Smooth-On Moulds be used for Baking?

Some Smooth-On Platinum Silicones are certified safe for food contact. Smooth-Sil® 940 , Sorta Clear® 40, Sorta Clear® 37, Sorta Clear® 18 and the Equinox® Series are suitable for making baking moulds and trays, ice trays, casting butter, chocolate and other applications used to produce foods.

These materials have been tested by an independent laboratory not owned by Smooth-On or affiliates. These products have been determined to comply with the total extractive limits when properly processed and heat cured. Refer to the technical bulletins for these materials for proper processing instructions (available at

Post cure requirement – After your Smooth-On rubber mould has been allowed to cure for 24 hours, expose to oven heat at 212° F / 100° C for 4 hours. Let cool and wash mould cavity thoroughly with dishwashing detergent/water solution. Rinse thoroughly and allow drying before using.

Compliance – The ingredients and ingredient levels in Smooth-Sil® 940, Sorta Clear® 40, Sorta Clear® 37, Sorta Clear® 18 and the Equinox® Series comply with 21 CFR 177.2600, rubber articles for repeated use subject to the total extractive limits as specified and published in the Code of Federal Regulations. FDA compliance does not mean that Smooth-Sil® 940, Sorta Clear® 40 and the Equinox® Series are FDA approved. To be approved, the user must also comply with ll applicable FDA requirements. Compliance with 21 CFR 177.2600 does not authorize use of the compound for the manufacture of baby bottle nipples.

Using Mold For Baking

Place Smooth-On rubber mould on a baking sheet for greater stability and handling.

Do not expose rubber to temperatures above 400° F / 204° C.

Do not place your rubber mould on an oven broiler. Silicone rubber does not distribute heat evenly, and this may also cause some rubbers to become heat damaged.

During the first use of your mould, keep an eye on how quickly your food is baking. Food in shallow moulds will cook faster than moulds in deeper depressions.

After use, clean moulds with soapy warm water and a soft sponge and rinse thoroughly between batches or prior to storing. You can dry the mould quickly in an oven. Bake for 5 minutes at 300°F / 150°C.

How should I store my rubber mould in order to extend its shelf life?

How you store your Smooth-On mould can have a tremendous effect on the shelf life or “library life” of your mould. A mould that is not stored properly could potentially be damaged and rendered unusable.

Proper mould storage

Clean the mould cavity with a sponge and soapy water and let dry. This will remove any harmful chemicals which could potentially shorten the life of your mould.

Cast plaster into your Smooth-On mould and let dry. Do not demould. You will be storing the mould with the plaster casting in it to help maintain dimensional stability, and reduce exposure to ambient moisture in the air.

If possible, place the mould with the casting in it in a black plastic garbage bag and seal tightly.

Place on a flat level surface. We’ve heard from Smooth-On customers that have accidentally stored their moulds with objects under them, causing the mould to permanently distort.

Store in a cool, dry environment out of ultraviolet light.

The one gallon units of Smooth-On are extremely difficult to open. Is there an easy way to get the lid off the container?

Smooth-On containers are securely sealed at our factory for maximum shelf life. These containers need to keep a perfect seal while they are shipped across country, and across the world.

Opening One Gallon Buckets

Using a razor knife, carefully cut each notch or “cut slot” around the perimeter of the lid (be careful when using sharp cutting tools.

Once each notch is cut, you can carefully pry the lid off. A flat head screwdriver can be used to help get leverage and take the lid off.

How do I break down and dispose of empty Smooth-On totes when my project is finished?

Smooth-On always aims to save our customers time, labor and disposal costs after you have finished your project. Smooth-On’s bag-in-a-box is designed for safe and easy break down and disposal. It is quick and simple. It only takes a few minutes!

Step 1 – Positioning Empty Tote:

The contents of the tote unit have been dispensed by our Smooth-On EZ~Mix meter mix machine. However, it is important to remember that there is often some residual material left inside the inner foil bag. To make breakdown cleaner and easier, position the empty tote on a pallet.

To prevent spilling of any material remaining in the inner foil bag, lift both sides of the front of the tote using two 4 x 6 blocks of wood (or similar); one on each side. Position the bag so the left over material will run back away from the valve.

Step 2 – Removing Tote Valve and Lid:

The next step is to remove the valve from the tote. Once the excess material has run away from the valve, remove the valve and the cardboard lid.

Use a pipe wrench to carefully lossen the 2″ PVC ball valve.  Once loosened, the valve can be removed by hand.  NOTE: If material begins to leak out of the valve, tilt the tote back until leaking stops.  Increase elevation of tote by adding height to the corner blocks.

Step 3 – Removing the Inner Foil Bag:

Once the value and cardboard lid are removed, it is time to remove the foil bag. Carefully lift the foil bag out of the tote unit. The foil bag with the residual material can now be safely disposed of, and any excess usable material can be salvaged.

Step 4 – Recovering Residual Material and Inner Foil Bag Disposal:

Waste not, want not! There will always be small amounts of material stuck in the corners of the tote. This excess can be drained out and saved for smaller projects. To fully empty foil bag, first reattach the 2″ PVC ball valve.  Using the tote unit’s cardboard shell for support, elevate the back end of the foil bag and position the closed valve over a clean 5-gallon pail.  The valve can then be opened, alllowing the residual material to flow out. Starting from back to front, squeeze the bag until all the leftover material is dispensed. Immediate store your extra Smooth-On material in an airtight, dry, container.

Applying XTEND-IT dry gas blanket will maximize the shelf life of remaining material.  Remove the ball valve and save for future use.  The empty foil bag can now be disposed of.

Step 5 – Breaking Down the Empty Cardboard Tote for Recycling:

The final step in the disposal of your Smooth-On tote is to breakdown the unit’s empty cardboard shell.  This is accomplished in a few simple steps.  First, remove the shell’s inner support structure.  Turn the cardboard shell on its side, providing access to the bottom of the unit.  Push in on the split bottom while pulling opposite corners to collapse and flatten the cardboard shell.  Once flattened, the cardboard shell can be recycled.  The pallet can be stored and reused.

Are Smooth-On materials safe to use?

General Statement – Smooth-On materials should be handled in the same way you would use household cleaning products. While some products are skin-safe, it is best not to let these products come into contact with eyes or skin. In the end, common sense should rule the day. For example, you would not want your children to use these materials.

Our liquid rubbers, plastics, foams, release agents, etc. are safe to use if directions are read and followed carefully. Not respecting these chemicals and exercising caution when using them can result in a trip to the hospital (see “sensitization” below). See your Smooth-On technical bulletin for recommend precautions before using any Smooth-On product.

Do not use Smooth-On moulding or casting materials in your home. Use them in your garage, dedicated workshop or basement with good ventilation. Keep children and pets away while using these materials.

First, read and understand the technical bulletin and Safety Data Sheet for the product you are using. A technical bulletin and SDS is available for any Smooth-On product at

There are different health risks associated with different materials.

Do not assume that because you are familiar with one material that the same handling procedures apply to a different material. Each Smooth-On product is uniquely formulated for various applications. Some materials may contain chemicals that other similar products do not.

Protect Yourself – You should wear long sleeve clothes and disposable gloves to minimize skin contact. Safety goggles will protect your eyes in the event that inadvertent splashing of a material occurs.

Skin Contact? Lightly wipe affected area immediately with solvent and then wash thoroughly with soap and water.

Eye Contact? If contaminated, flush eyes with water for 15 minutes and seek immediate medical attention.

Ventilation – Avoid breathing in plaster dust, mist from aerosol sprayers or fumes of any kind, etc. These materials may irritate the lungs and eyes during use. When using any material associated with mould making and casting, you must have “room size” ventilation (400 ft2 / 38m2) or greater.

If using Smooth-On Moulding and Casting materials on a regular basis, you should install an external ventilation system in your workshop above your work space. Always work close to this vent when moulding and casting, especially when using liquid or powdered products. Wearing a NIOSH approved respirator will further minimize risk of inhalation.

Spraying Material – If you are spraying rubber, plastics or foams, try to do your spraying outdoors in an open space. Any residual material from your sprayer may adhere to your table, walls and other surfaces. For safety, and cleanliness, designate an isolated area for spraying your mould rubber, plastic or foam. Regardless of spraying outdoors or inside, anyone in the spray area must wear a NIOSH approved respirator and disposable gloves at the very least.

Using Aliphatic Isocyanates – There is a class of polyurethane chemistry known as “aliphatic isocyantes” that require extra handling precautions. These are for “industrial use” only and should not be used by students, hobbyists, etc..

Which Smooth-On Products Are Aliphatic Isocyanates?

Any “Crystal Clear” liquid plastic product.

SMASH! Plastic

Clear Flex 50 & 95 Urethane Rubber

Task 12 Plastic

If using one of these products, you must wear a NIOSH approved respirator, long sleeve garments and disposable gloves to avoid skin contact.

Sensitization – if you are having an allergic reaction, such as hives or respiratory distress, while using Smooth-On polyurethanes, stop using them and seek immediate medical attention.

Symptoms of Sensitization Include; if you are having trouble breathing, experiencing throat discomfort, itching eyes, and/or a skin rash, you may be having a reaction to these materials.

Cease and Desist – Permanently. If you experience these symptoms following any exposure to a Smooth-On urethane product, chances are you have become sensitized and you will experience a reaction every time. At this point, you should avoid using all urethanes. Seek other Smooth-On products for all of your future projects.

What is Smooth-On's Warranty Policy?

Smooth-On will warranty silicone products for six months from date of manufacture in unopened containers stored at 73 F/23 C.  Elevated temperatures will quickly shorten the shelf life of silicones.  Smooth-On will warranty all other products for 1 year from date of manufacture in unopened containers stored at 73 F/23 C.

Smooth-On Quality Control Testing

Smooth-On will not use unsafe ingredients in our products. Smooth-On has an extensive quality control program that tests the quality of incoming raw materials. Our raw materials are delivered to our factory in large tanker cars.  Material cannot be off loaded from delivery tankers unless they are tested and meet our quality control standards.  If it does not pass our incoming quality control testing, the material is refused and trucked back to the manufacturer.

We then test each batch of material while the batch is being blended in our large mixing vessels (work in process testing).

Finally, the material is tested a final time before being dispensed into packaging containers.

Probability of Defective Material

It is extremely rare that a material makes it past our quality control laboratory and is shipped to end users.  People often believe that material that did not work as they expected is defective.  User error, material incompatibility, cure inhibition and other non-material related variables are usually the cause.

To help prevent any Smooth-On products being damaged or misused you can refer to our FAQ page. Also consult your Smooth-On product’s technical bulletin for details on proper storage and usage.

Smooth-On makes millions of pounds / kgs. of silicones, urethanes, epoxies, polysulfides, release agents and other materials every year.  Our batch sizes can be as large as 30,000 lbs. / 13,600 kgs. and the material is packed into tote units, drum units, 5 gallon units, one gallon units and trial units.

We make thousands of units from a single batch of material. In the event that a batch is defective, Smooth-On’s customer service will hear complaints from hundreds of customers across the world in a short period of time.

Smooth-On makes every effort to investigate claims of defective product. If a defective batch is confirmed, we will make every effort to track the defective shipments, and recall the bad material. Smooth-On will make arrangements to replace defective materials.

What You Can Do To Verify If A Material Is Performing Normally . . .

Smooth-On material that is beyond shelf life or has been opened may not perform properly. Always make sure your material is within the prescribed shelf life before beginning your project.

Re-read the technical bulletin, and take all precautions necessary to remove factors which may negatively affect your materials. Make sure you know the correct mix ratio, working time, etc. for the material.  Make sure the material is at room temperature (73 F / 23 C) and you are in a low humidity environment (less than 50% RH).  Pre-mix both Parts A & B individually as directed by the technical bulletin.

Carefully measure, mix at least 100 grams total of material into a new, clean plastic cup and allow material to fully cure as directed by the technical bulletin.  If the material cures in the cup, but is not curing against your model, in the mould or against a surface, the problem is not the material.  You can then visit the FAQ section of help trouble shoot the cause of your problem.

If material is partially cured in the cup, repeat test making sure that the material is at room temperature and you mix as directed by the technical bulletin. Partially cured material is often a symptom of a cold environment and/or insufficient mixing.

If, after testing, you suspect that a material is defective. . .

You can contact Smooth-On either by phone or e-mail.

E-Mail;  send an e-mail to the Smooth-On technical service department by clicking here.  Provide the name of the product, the size container, when you purchased it, where you purchased it and the lot numbers provided on the product labels or outside of the box indicating “Lot #”.

By Phone; call (610) 252-5800 and ask for the technical service department.  Provide the name of the product, the size container, when you purchased it, where you purchased it and the lot numbers provided on the product labels or outside of the box indicating “Lot #”.

After receiving your information, what does Smooth-On do?

Our Smooth-On customer service reps check our “customer complaint log”.  If we see at least 3 complaints about the same product and lot number, we automatically test retained material that we store at Smooth-On for a period of 1 year after a batch of material is made and shipped.  If confirmed to be defective, we make every effort to trace shipments and contact recipients who may have received this material.  Smooth-On will then make arrangements to replace the material.

If there are fewer than three complaints, our representatives will try to help you troubleshoot your product and help determine why it is not performing as expected. As a part of the troubleshooting process, you may be asked to email images of your project, send a sample of your cured material or send us the unused material remaining in the container. Smooth-On will do our best to help determine the exact nature of your problem.

Packaging Problems & Issues – Product’s packaging can be damaged in transit, which may introduce contaminants or moisture. If you notice your product is damaged in transit, exhibiting leaking, etc., you should report it within three business days of receipt of material to the seller where you purchased your Smooth-On products.

I want to heat cure my mould, but and I cannot use an industrial oven. Is it safe to use my kitchen oven instead?

You should NEVER use your kitchen oven for mould making or casting applications. Smooth-On rubbers and plastics may release harmful fumes when heated, and may also damage your oven.

If you don’t have access to an industrial oven, you can create an alternative by building a “hot box” out of materials commonly found at Do It Yourself store or home center. You can use the hot box to accelerate the cure of rubbers and plastics, to post cure castings, and to pre-heat moulds for casting Crystal Clear Series resins.

Smooth-On’s FAQ page offers instructions on how to build your own hot box for use at home without risking your kitchen appliances.

purchased a two-part mould rubber, but one of the containers is only ½ full. Is this a mistake?

Appearances can be deceiving. All Smooth-On products are measured and packed by weight. This might result in one container having less liquid by volume, but when mixed correctly there should be enough of parts A and B to properly cure all of the product.

For example, a gallon unit of Vytaflex 20 urethane mould rubber contains 16 lbs. of liquid in both sides (A + B) and is 7/8 full by volume. A gallon unit of Brush-On 40 contains 18 lbs. of material – liquid in the Part A side and a heavy paste in the Part B side. Due to the density of the paste material, the Part B will only fill a gallon bucket ½ full volumetrically.

Don’t estimate the amount of material needed for your application by volume. All Smooth-On mixing instructions specify to mix by weight for a reason. Always use a weight when mixing these products. Correlating the cubic inch per pound yield of the material with the cubic inches of your original (and possibly your mould box) is a more accurate determination for your material requirement.

What are the effects of cold weather on urethanes or silicones?

Cold weather will not permanently harm your Smooth-On urethane or silicone materials. However, it will cause these materials to thicken and separate. If a customer tries to use the material while it is cold, it will not cure.

Always allow the materials to reach room temperature (at least 73°F/23°C) in the containers before opening. Depending on how long the materials were exposed to cold temperatures, and the size of your container, it can take several days to bring them up to 73°F/23°C.

Urethane or Silicone Rubber – Bring material up to room temperature. Before using, open Part A container and mix thoroughly for about 3 minutes. Use the flat side of a mixing paddle to scrape the sides and bottom for excess separated material. Repeat this process with part B. Silicone curative Part B in glass bottles can be shaken before dispensing.

Urethane Plastic – Bring material up to room temperature. Trial or 1 gallon units can be shaken thoroughly before dispensing material. 5 gallon buckets should be opened and pre-mixed with a flat edge stirring paddle for 3 minutes before dispensing material.

How should I prepare my work surface before applying Smooth-On epoxy adhesives?

Smooth-On has prepared a guide for preparing your work surface for working with Smooth-On epoxy adhesives.

Is there an easier way to pour material from a heavy 5 gallon pail?

1. Be sure to read technical bulletin for each Smooth-On product. Some materials require pre-mixing before using.

2. While the container is upright, remove protective cover and cap from the Reike spout with a screwdriver. Pull to remove the plastic seal inside the spout.

3. On a level table, place the 5 gallon container on its side, and toward the edge of the table. Make certain that the pour spout is closest to the ceiling (12 o’clock position).

4. Slowly roll the 5-gallon container so that the material begins to flow out of the container in a slow and uniform stream. This will help eliminate air being introduced into the mixture and prevent spillage. Roll the pail back to the 12 o’clock position to stop the flow.

Note: If the spout is rolled all the way to the bottom (6 o’clock position) the pressure will cause the material to flow out quickly. This will make spills highly likely. It is recommended that you roll the pail slowly until a controlled stream pours from the spout.

How are these materials packaged?

Smooth-On’s rubbers, plastics, foams and other materials come to you packaged in plastic or metal containers of various sizes. What determines the “pack out” configuration of a rubber, plastic or foam system is:

1) the mix ratio of the system (A + B)

2) the viscosity of the material

3) the density of the material.

Unit sizes (A+B) include:

Trial Units – come to you packaged in pint bottles, quart bottles, pint jars or quart jars.

Gallon Units – packaged in gallon plastic buckets, metal cans or glass bottles.

5 Gallon Units – packaged in 5 gallon plastic and metal buckets.

55 Gallon Units – packaged in metal or plastic drums

Tote Units – equal 5 drum units. Packaged in a foil bag inside a heavy duty cardboard box.

When mixing your two-part Smooth-On product, always measure by weight. Use a scale when determining how much of each part is required, not a measuring cup.

Materials are packed by weight – don’t judge by appearances.

Appearances can be deceiving. All Smooth-On products are measured and packed by weight. This might result in one container having less liquid by volume, but when mixed correctly there should be enough of parts A and B to properly cure all of the product.

For example, a gallon unit of Vytaflex 20 urethane mould rubber contains 16 lbs. of liquid in both sides (A + B) and is 7/8 full by volume. A gallon unit of Brush-On 40 contains 18 lbs. of material – liquid in the Part A side and a heavy paste in the Part B side. Due to the density of the paste material, the Part B will only fill a gallon bucket ½ full volumetrically.

Don’t estimate the amount of material needed for your application by volume. All Smooth-On mixing instructions specify to mix by weight for a reason. Always use a weight when mixing these products. Correlating the cubic inch per pound yield of the material with the cubic inches of your original (and possibly your mould box) is a more accurate determination for your material requirement.

I’ve noticed variations in colour between batches of Smooth-On Mould rubber. Will a variation in colour affect material performance?

The colour of Smooth-On’s products can vary slightly from batch to batch. This is normal, and does not affect the material’s performance, pot life or shelf life. All batches are tested before being packaged and shipped out to our Smooth-On customers. Use your raw materials with confidence!

What is Smooth-On's Return Policy?

If you purchased material from a Smooth-On distributor, please contact the distributor to discuss their returns policy. Every Smooth-On distributor will have their own return and exchange policy.

If you purchased material directly from Smooth-On, your product must:

Please contact Smooth-On at (610) 252-5800 if you have questions regarding this policy.

What is the benefit of using Body Double rather than Alginate for life casting?


Alginate has a short window of opportunity for casting. Alginate will begin to shrink shortly after the mould is made. To make an exact casting of the original mould, the casting must be poured shortly after the Alginate has cured. Alginate will quickly shrivel up and become unusable.

Smooth On’s Body Double is made from durable silicone rubber which does not shrink, and has a much longer shelf life.

Strength and Durability

Alginate made a delicate mould. Alginate moulds are prone to rips, and will only survive one casting. In addition, because of its low durability, Alginate limits your castings to materials such as plaster.

Smooth-On’s Body Double is highly durable, heat resistant, and can survive multiple castings. You can cast almost anything into your Body Double mould. You can cast liquid plastics, wax, plaster, low temperature melt metal alloys, concrete and other materials to make your reproduction.

Can I cast hot wax into an Alja-Safe® alginate mould?

A: Yes, it is possible to cast hot wax in an Alja-Safe® mould. However, hot wax is difficult to cast solid. The best casting technique is to build layers of wax into the mould.

Fill your Smooth-On Alja-Safe® mould cavity to the top with the hot, liquid wax and then pour it out. Wait a few minutes for the first layer to set up, then pour in and out again. Let it set again and pour more wax in and out again.

The finished wax casting thickness should be about 1/4″ – 3/8″ (0.60 cm – 0.95 cm).

Your casting needs to cool for several hours before demoulding. Even mildly warm wax will lose detail and break off delicate pieces, such as fingers, easily.

How much Body Double silicone do I need?

Smooth-On has a useful guide which can help you determine how much Body Double you will need for making a mould of a face, head, hand, torso and more.

In what ways is Alja Safe better for life casting than Body Double?

1.Smooth On’s Alja Safe alginate is more cost effective than Body Double. Alginate products cost less to purchase than Body Double.

2. While Body Double rubber will bond with many surfaces, alginate does not stick to anything. In most cases, you will not need to purchase a release creame to use alginate. You can make a mould of the hair on your head with alginate by using hair conditioner as a release agent. You can’t make of mould of the hair on your head with Body Double. The result would be painful! Always use a plastic bald cap when using body double for life casting.

Which is the superior Smooth-On product for highly detailed life casting, Alja Safe or Body Double Silicone?

Both of these Smooth-On products work well and will capture detail down to the fingerprint. See the technical bulletin and life casting FAQ page to determine which of these products will work best for your application.

Is there latex in BODY DOUBLE?

There is no latex in Body Double, so there should be no issues for people with latex allergies. In fact, the presense of latex will actually prevent silicone based rubbers, such as platinum cured Body Double, from curing. When using Smooth-On Body Double, always use a plastic bald cap instead of a latex bald cap.

What Smooth-On products do I need to create a Silicone Gel-Filled Makeup Appliance?

Here is a basic list of Smooth-On materials of materials you will need to make a Gel-Filled makeup appliance:

A 2-part mould created from Neo Matrix, another gypsum or other rigid material

Dragon Skin Silicone for creating the membrane encapsulator and making the gel

Slacker Tactile Mutator added to Dragon Skin to create a silicone gel

Silc-Pig Pigment for pigmentation of the silicone

Skin Tite Adhesive to adhere the piece to the skin

Optional items:

Plat Cat Platinum Silicone Accelerator to accelerate the cure of the silicone rubber

Psycho Paint to paint your new Gel-Filled appliance.

Is there any way to prevent sweating off Skin Tite® appliance adhesive?

Due to the acidic nature of human perspiration, sweat will break down makeup prosthetic adhesives, and Skin Tite® is no exception. Use a preventative measure to extend the life of your Skin Tite®. Premiere Products Top Guard or Michael Davy’s Sweat Stop will help keep your prosthetic appliances from peeling off.

Another option is to wait until the Skin Tite® silicone is more fully cured before applying the piece. Often times people apply the piece when the Skin Tite® is uncured, causing their model to begin to perspire right away, and prevent a proper bond. Waiting a few minutes until the Skin Tite® is more cured can help.

How do I make the Skin Tite® less tacky?

Like other spirit gums and prosthetic adhesives, Smooth-On’s Skin Tite® cures with a tacky surface. This helps create proper adhesion between the skin and the prosthetic.

Using a “neutral set” makeup powder will help reduce the tacky feel of Skin Tite® appliances. A small amount is usually all that is needed to reduce the tacky feel of Skin Tite®.

Do I need to put release cream on body hair when using Skin Tite®?

Smooth-On’s Skin Tite® is safe to use on your body hair. Our Skin Tite® is specially formulated not to bond to body hair. Use Skin Tite® to apply prosthetics to body hair, eyebrows and even beards without fear of painfully removing the appliance afterwards.
