The products we manufacture are available in what we refer to as “standard production color” or as a clear product where by color pigments must be purchased separately and added at the time of use. Our Speedliner Spray on Truck bed liner product, the Purecast rope coatings and our StyroSpray are examples of products which must always have color pigments added at time of use. Color pigments are usually made from powdered minerals and these minerals can in some cases react with our products in storage causing the color to change or causing the product to thicken and spoil in the storage container (orange & yellow). To avoid storage problems, color pigments should in some cases only be added at the last minute when the product is being mixed and applied. If you are using color pigments from other suppliers we recommend you perform a small cup test to determine if the color pigment will work correctly with our products.
If a product does not react with color pigments in storage we may add color pigment at the time of manufacture. When we add color pigment to a product during manufacturing we call this the “standard production color”. This is the color you will automatically receive when placing an order for our TrueCast mold making rubbers or for one of our SpeedSet products or casting resins. If you are purchasing smaller 2 quart or 2 gallon kits the product will automatically arrive in our standard production color. When placing orders of 10 gallon kit size or larger we offer customers the ability to request a nonstandard color at no additional charge, see listings below of standard production colors and optional colors we offer. Customers must remember to request a nonstandard production color at time of ordering. Nonstandard Colors are offered on a best effort basis, we cannot guarantee perfect color consistency between production runs or to color match a specific color. Color options depend on the individual product you are ordering and the availability of a particular color pigment in our inventory. Some of the rigid and semi rigid casting resin products we offer are not recommended for outdoor long term UV exposure unless painted or colored with darker color pigments. Adding a medium or dark color pigment will increase long term UV resistance and will hide color change which results from UV exposure. It is generally better to use darker colors like black, shades of gray, brown, tan or even darker blue colors to reduce the visible effects of long term UV exposure in casting resins.
In some products like our Insta-Gel Spray on rubbers we use color to alert customers to mixing problems. When A and B components are correctly mixed the cured Insta-Gel Spray rubber has a consistent distinguishable color, see listing below. For the StyroSpray 1000 product we add a small amount of white Titanium oxide color pigment to indicate if the part B component was properly mixed before use. The part B component settles out quickly in storage and must be mixed up before use. If a customer reports the StyroSpray product is not curing properly or exhibits a darker than usual color we have an indication the product is not being mixed thoroughly enough or in the proper mix ratio.
We offer 3 basic types of color pigments, translucent dyes, SL series pigments and RV series pigments. The correct type of color pigment must be used with each product for best results, see listing below for correct type of color pigment for each product. We offer color pigments and dyes in small or large quantities, ½ pint to 5 gallon containers. SL series color pigments are sold in pre-measured 4 ounce tubes, the RV series color pigments are sold in metal cans ranging from ½ pint to 5 gallon shipping quantities.
Translucent dyes are translucent color pigments. They are typically used to tint our Crystal Cast clear casting resins. They are highly concentrated color dyes added in small amount to add color tint and maintain some level of transparency. Translucent dyes are offered in 4 primary colors; these primary colors must be mixed to achieve a full color pallet. If you wish to achieve an opaque color with our CrystalCast clear casting resins use the RV series color pigments. The Translucent dyes are also used to color our TrueCast and InstaGel rubber mold making products. See complete product listing below. Color pigments are usually added into part B component. We do not usually add pigments into part A component because some color dyes may make the part A clot or thicken in storage container.
The SL series color pigments are opaque color pigments, they provide a dense non transparent coloring. We currently offer 18 color options in our SL series of color pigments. These color pigments are provided in pre measured 4 fluid ounce volume tubes (weight of color tubes varies by color but all contain 4 liquid ounces volume). The Speedliner, Purecast, TrueKote, FiberLock and ProtoCast products are compatible with the SL series pigments and are usually added at a rate of one tube per mixed gallon. If you are using one of our Top Coat products, like Top Coat 6, 7 or 9, we recommend mixing in more color pigment, 1 tube of SL pigment per mixed quart or 4 tubes per mixed gallon, see product listing below. Color pigments are usually added into part B component. We do not usually add pigments into part A component because some color pigments can make the part A clot or thicken in storage container.
The RV series color pigments are opaque color pigments, they provide a dense non-transparent coloring. The RV series pigments are compatible with most of our casting resins like TrueCast, Speedset, StyroSpray, and UraGel products see complete product listing below. Color pigments are usually added at a rate of ½ pint per gallon of part B; pigments are only added into part B component. Mix in ½ pint into part B component, then with equal amount of uncolored part A component.
We do not usually add pigments into part A component because some color pigments can make the part A clot or thicken in storage container.
Here is a complete alphabetical listing of the products we manufacture, standard production colors and compatible color pigment series for achieving special colors.
Clear Masonry Brick Sealer
This product is always supplied clear without any color additives.
CrystalCast clear casting resins
The standard production color of all CrystalCast products is clear. Customers may use translucent dyes or RV series color pigments at time of use to add coloration. It is possible to swirl translucent dyes or RV series color pigments in the CrystalCast clear resin to create mixed color effects. CrystalCast products can also be colored with holographic or pearlescent color change reflective pigments available from www.silberline.com or www.spectratek.net and other suppliers. CrystalCast products can also be colored with glow in the dark phosphorescent pigments available from www.umccorp.com and other suppliers. Holographic pigments work much better with our CrystalCast clear casting resins than traditional metallic pigments. Holographic pigments disperse better in the resins and provide a brighter more reflective surface than traditional aluminum metal flake pigments. The holographic pearlescent pigments provide a vibrant color changing effect as light strikes the surface of cured resins.
FiberLock product is a dip coating used for coloring rope, cord, fabric or netting. You may order this product clear and purchase colors separately adding in color at time of use or you may select from any of our SL color pigment options and we will color it at time of manufacture at no additional charge. Sometimes customers prefer to color at time of use so they have the ability to apply many different colors to their rope.
Foam-Rigid 3 pound density expanding molding foam
The standard production color for this foam is without color, natural yellow color when cured. RV series color pigments can be ordered separately or you may request one of our RV series colors at time of manufacture. This foam yellows quickly with UV exposure in outdoor installations, therefore, we recommend it be painted with a solvent or water based paint finish. If you color this foam we recommend you use darker color pigments to hide color change resulting from long term UV exposure.
Foam-Flexible Expanding Foams 300, 600 & 800 RV series color pigments
The standard production color for these foams is without color, off white color when cured. RV series color pigments can be ordered separately or you may request one of our RV series colors at time of manufacture. This foam yellows quickly with UV exposure. If you color this foam we recommend you use darker color pigments for outdoor installations to hide color change resulting from long term UV exposure.
The standard production color is cream/off white, we do add color pigment during manufacture. RV series color pigments may be ordered separately or you may request one of our RV series colors at time of ordering. We recommend you use darker color pigments for outdoor installations or painting over it with water or solvent based paints to hide color change resulting from long term UV exposure.
The standard production color of this product is transparent blue/green. We do not offer any color options for this product because it is typically disposed of shortly after use.
The standard production color of this product is transparent off white when cured with water. We do not offer any color options for this product because it is typically disposed of shortly after use.
Insta-Gel brush on rubbers for mold making
Insta-Gel 20 standard production color is purple. Insta-Gel 30, 40 & 50 standard production color is Light Blue. In our Insta-Gel rubber products we use translucent dyes for all standard production translucent colors. RV series color pigments can also be used to create opaque colors if desired. Darker RV series opaque color pigments should be used to hide color change from long term UV exposure or our Top Coat number 9 can be used with SL series color pigment to add a colored top coating for color and UV protection.
Insta-Gel Spray on rubber for mold making or rubber skins
Insta-Gel Spray 20 standard production color is purple. Insta-Gel Spray 30 is green; Insta-Gel 40 & 50 standard production color is light Blue. In our Insta-Gel rubber products we use translucent dyes for all standard production translucent colors. RV series color pigments can also be used to create opaque colors if desired. Darker RV series opaque color pigments should be used to hide color change from long term UV exposure or our flexible Top Coat number 9 can be used with SL series color pigments to add a colored top coating for color and long term UV protection if desired.
Standard production color is white no other color options are available for this product
Standard production color is white no color is added. SL type color pigments can be requested at time of production or may be purchased separately and added at time of use.
Standard production is light gray no color is added, sand stone color results from ceramic filler. SL type color pigments can be requested at time of production or may be added at time of use.
Standard production color is white no color is added. SL type color pigments can be requested at time of production or may be purchased separately and added at time of use.
The PureCast products are colored with our SL series color pigments; please see listing at the bottom of this page. The SL series pigments are available in pre measured 4 ounce tubes or in larger volumes it is packaged in metal cans ranging in size from ½ pint up to 5 gallons. We recommend using 4 ounces by volume of SL series color pigment per mixed gallon of the Purecast product. The color pigments should always be added into the part B component before mixing with the part A component. The SL color pigments should only be mixed into the product just prior to mixing and application. Purecast reacts with some color pigments in storage so we cannot add color pigment to this product at the time of manufacture, it must be mixed into the Purecast minutes before you mix and apply the product.
Standard production color is clear amber; SL series color pigments must be purchased separately and added at time of use. We offer a selection of 18 colors in pre measured 4 ounce color tubes. If you wish to apply this product in white color or holographic pearlescent colors or in light metallic filled colors it must be top coated with our Top Coat Number 6 product. Speedliner is applied much thicker than ordinary paint finishes, metallic or pearlescent color pigments are designed to float or align themselves in paints as they are spray applied. The thickness of Speedliner does not allow these types of color pigments to rise to the surface and present themselves as designed. If you wish to achieve a metallic or pearlescent reflective finish we recommend you add these pigments into our Top Coat Number 6 product and top coating over the Speedliner. When applying Speedliner in white we also recommend using our Top Coat Number 6 product with white SL series color pigment and top coating over the Speedliner. White Speedliner without top coating will eventually yellow in outdoor applications from long term UV exposure or become stained by air pollutants, chemicals or leaves which are allowed to sit for long periods of time in a truck bed liner application.
SpeedSet 350 standard production color is yellow color. SpeedSet 371 standard production color is milky clear color. SpeedSet 401 standard production color is gray color. RV type color pigments may be added at time of manufacture or purchased separately and added at time of use.
Standard production color of StyroSpray 1000 is off white color. RV series color pigments must ordered separately and added to the product at time of use. We cannot add color pigments to StyroSpray 1000 at time of production because some pigments react in storage with this product. We add a small amount of white pigment into the Part B component at time of production. White
pigment makes the product more visible during application to foam and it also reminds customers that the Part B component must be stirred up before each use. The presence of white pigment in the base product will make color pigments appear somewhat more pastel when added. Black color pigment produces dark gray, dark red pigment becomes more pastel red; this will be true with any color pigments you add to the StyroSpray 1000 product. Maximum color pigment loading is ½ pint RV series pigment per gallon of part B component, which is then mix with an equal amount of un-pigmented part A. It is possible you will use less then ½ pint to achieve the color density you need, but do not add greater amounts of color pigment or it will soften the product.
StyroPrime foam sealer, standard production color is white no other color options are available
Top Coats Number 6, 7, 9
Top Coats 6, 7 and 9 standard production color is clear, these top coatings can be applied as clear coats or pigmented with SL series color pigments. Top Coats are typically used to add color and UV stability over other products which may yellow with long term UV exposure. Top Coat Number 9 is a flexible clear coating which is sometimes used to add color and UV stability to our flexible rubber products like TrueCast and Insta-Gel. Glow in the dark phosphorescent and holographic pearlescent pigments may also be used. Top Coats require a greater amount of color pigment loading, 1 tube of SL series color pigment (4 fluid ounces) is recommended per mix quart of Top Coat 6, 7 or 9. Top Coat products may also be colored with holographic pearlescent color change reflective pigments available from www.silberline.com or www.spectratek.net or other suppliers. They may also be colored with glow in the dark phosphorescent pigments available from www.umccorp.com and other suppliers.
TrueKote CS, 100, 150S and 155S
TrueKote CS, 100, 150S and 155S standard production color is clear amber SL series color pigments must be purchased separately added at time of use. We offer a selection of 18 SL series color pigments in pre measured 4 ounce color tubes. Typical color pigment loading for these products is 1 pre-measured tube of SL series pigment per mixed gallon. Remember only add the color pigment into the part B component just prior to mixing and applying this product.

In our TrueCast rubber products we use translucent dyes or opaque RV series color pigments to color them. Nonstandard colors may be requested at time of production or customers my request clear and add translucent dyes or RV series pigments at time of use.
UraSeal 210: Standard Product color is medium gray; other RV series colors are available on request.
UraGel 770: Standard Production color is medium gray; other RV series colors are available on request.
Surface Primers 200, 450, 460 and 700 adhesion promoters
Standard production color for primers is amber clear no color is added. SL type color pigments may be added at time of use to increase visibility during primer application if needed. If color pigment is added only trace amounts of pigment should be used, less than 1% by weight maximum. The addition of greater amounts of color pigment into surface primes will reduce their effectiveness and result in coating delaminating. Maximum amount of color pigment you can add to any primer is 1 fluid ounce per mixed gallon, greater amounts of color can cause the primers to be weak or not cure properly.
Translucent dyes are very powerful pigment concentrates; it may only take a few drops in a quart or gallon of clear casting resin to achieve the desired translucent color. We offer primary colors which must be mixed to achieve other non primary colors. We offer translucent dyes in half pint, pint and quart shipping quantities
Pigments are typically used for coloring opaque non translucent colors; translucent dyes are used in applications where some translucent color effect is desired. Customers will use our translucent dyes to tint our clear casting resins where they desire to maintain some amount of transparency. Translucent dyes can be added at a rate of 1cc per gallon of component B. Color dyes are highly concentrated add progressively to avoid over coloring.
List of SL series color pigments packaged in 4 fluid ounce pre measured tubes
Listing of RV series color pigments
Maximum amount of RV series color pigment which should be used with any of our products is 3 % by weight. You may use less pigment but not more than 3% or it will begin to weaken or soften the product.
Red Iron Oxide
Yellow Iron Oxide
Listing of translucent dye color pigments.
These pigments are highly concentrated usually requiring only 1 cc per 2 gallon kit of clear resin. These primary colors must be mixed to achieve a full color pallet.
Metal powders for polyester resins are available from www.zinccorp.com and other suppliers.
The HydroSpan 400 product was invented by Industrial Polymers for reducing the size of 3 dimensional objects while maintaining high surface detail. The HydroSpan 400 product is a urethane resin which quickly cures when mixed with ordinary tap water. We recommend using cold water (ice cold water) to extend the very short working life of this product. You must create a mold of the original object you which to shrink in size and then fill the mold with HydroSpan 400. The HydroSpan 400 will rapidly cure in your mold within minutes. Remove the HydroSpan 400 casting from your mold and place in a low humidity environment to begin the reduction process. You have only 1 to 2 minutes to pour this material into your mold after mixing with cold water before it cures. See video demonstration on this page. The amount of water used in the reaction depends on the amount of reduction you wish to achieve. See HydroSpan 400 technical data information PDF file on this page or quick reference chart bottom of this page.
The HydroSpan 400 shrinks proportionally as water evaporates out of the cured product. You may use a food dehydrator to speed the shrinkage process or simply leave the casting in a low humidity environment for it to shrink; it produces very accurate reductions of any casting. Most of our experience with this product has been with shrinking objects with a starting size of approximately 6 inches in diameter. Very large castings may be more difficult to shrink because it will take much longer for the water to evaporate from the HydroSpan 400 casting. You must monitor the shrinking process until the desired size is achieved. When the desired reduction size has been achieved you will make your new production mold from the reduced HydroSpan 400 casting. You may use molds made from urethane rubber, silicone rubber, metal or plastic to cast HydroSpan 400. Silicone spray mold release or wax based release agent must be used to prevent sticking of HydroSpan in your mold, except for silicone rubber molds which are naturally releasing.
One customer reported that he was able to shrink a larger casting by segmenting the casting into smaller pieces with a sharp knife, shrinking the pieces to the desired size, then gluing them back together. A new mold was then made from the reassembled reduction. HydroSpan 400 is sold in quarts, gallons or 5 gallon quantities please call or email us for current pricing and delivery 713-943-8451 / 800-766-3832 email. See Technical Information and Material Safety Information on this page for more complete instructions. (We also manufacture an enlarging product see HydroSpan 100 product page on our web site for video demonstration)

HydroSpan 100™ works like a 3 dimensional copy machine enlarging any shape or design in near perfect proportion and detail. With HydroSpan you can increase the size of patterns, molds, art castings, foundry molds, fossil patterns or original art works without sculpting new masters. Original art can now be replicated in various sizes to customer requirements without sculpting new masters. Imagine how much time you will save using this product.
We invented HydroSpan 100™ for a customer needing a fast economical way to enlarge seashells, fossils and other common items for museum exhibits. Sculpting larger versions of objects is tedious and time consuming. With HydroSpan 100™ you can directly enlarge items by simply soaking your HydroSpan 100 casting in water. We begin by making a silicone rubber mold from any object we wish to enlarge. We Then pour HydroSpan 100 into the mold to create a HydroSpan 100 casting of the original item. The HydroSpan 100 casting is later removed from the mold and soaked in ordinary tap water to begin the expansion process. Within days the HydroSpan casting gradually expands to larger size, fully expanded the HydroSpan casting will grow 60% larger than original size. By creating progressively larger molds from larger HydroSpan 100 expansions, it is possible to expand a silver dollar to the size of a dinner plate. HydroSpan 100 is sold in quarts, gallons or 5 gallon quantities please call or email us for current pricing and delivery 713-943-8451 / 800-766-3832 email (we also manufacture a shrinking product see HydroSpan 400 product page)
HydroSpan 100 is a flexible urethane casting resin which gradually absorbs ordinary tap water increasing size in near perfect detail. When liquid water touches the surface of HydroSpan 100 it is attracted to the atomic charge of the polymer molecules. As water is absorbed the polymer matrix stretches to accommodate the in coming water. The absorbed water is so tightly held inside the HydroSpan 100 polymer it appears almost dry to the touch when fully expanded. Even cutting or crushing the polymer will not easily release liquid water. Migrating water molecules inside the HydroSpan 100 uniformly surround each polymer molecule, evenly stretching the internal polymer matrix in all directions. Through this process HydroSpan 100™ produces near perfect expansion of molded shapes by soaking in ordinary tap water.
HydroSpan 100™ is a safe easy to use 2 component flexible urethane. It is nonhazardous for shipping purposes and produces no odor. It has a mix ratio of 2 parts A to 1 part B component by measured by volume, working life is 10-minutes, full cure time 24 hours. Hardness of cured HydroSpan 100 (before soaking) is 45 Shore A / hardness of expanded HydroSpan™ (after water soaking for 14 days @ 72° F ) is 35 Shore A. Maximum Percent increase in size is +60%. To calculate size of fully expanded shape multiply starting dimensions by a factor of 1.6. For example an object which measures 10 inches tall, will become 16 inches tall after one full expansion (10 X 1.6 = 16). Partial expansions of less than the full +60% are possible by early removal from water soaking. Partially expanded castings may have distortions because thin wall areas will increase in size more rapidly than thick sections. Place partially expanded castings in an air tight plastic container until distortions equalize away.
HydroSpan 100 is mixed by hand stirring or electric drill with jiffy mixer attachment, the color is transparent blue.
We recommend using silicone rubber molds to avoid the use of a release agent which can slow the absorption of water and subsequent expansion process. The time required to complete the expansion process will very with the thickness of the HydroSpan 100 casting. Thin castings up to ½ inch thick will fully expand In several days. Thicker castings with a cross thickness of 2 or 3 inches will require 2 to 3 weeks of water soaking to achieve full expansion. Some temporary distortion occurs as HydroSpan begins the expansion process because thin walled elements tend to expand more rapidly. Water ports can be installed in thicker castings to reduce cross thickness and speed expansion. See Technical Information and Material Safety Information for more complete instructions.
