We offer a few options for creating colors with your epoxy project.

Epoxy Pigment Concentrates:

Epoxy Pigment Concentrates are specifically formulated for all System Three liquid epoxy resins. They are available in 7 standard colors and can be blended with each other to create additional colors. Simply add the pigment concentrate to the Resin (Part A), then mix the now pigmented resin at the specified ratio with the Hardener (Part B). The Epoxy Pigment Concentrates can be added up to 10% by volume to achieve full thin-film opacity without changing the performance of the cured product.

CastFX Liquid colorant:

CastFX Liquid Colorants are designed to work specifically with System Three RiverCast, MirrorCast, and MirrorCoat. Add a little for a transparent effect or add up to 4 ounces per mixed gallon for complete opacity of your casting project. CastFx Liquid Colorants can be intermixed with one another to create your own unique color blend and blended with CastFX Dry Metallic Pigments to create stunning, one-of-a-kind effects.

CastFX Dry Metallic Pigments:

CastFX Dry Metallic Pigments are powders that can be added directly to System Three RiverCast, MirrorCast, and MirrorCoat. These Pigments are non-reactive and can be incorporated into the mixed epoxy at any ratio. CastFX Dry Metallic Pigments add a stunning pearlescent effect to our resin systems and can be intermixed with one another or blended with Cast FX Liquid Colorant to create your own unique color blend.

Other colorants, dry pigments, and dyes have been shown to be compatible with the System Three products. You should always test other supplier's colorant material to ensure you are happy with the results before using it with a System Three Epoxy.

Bubble formation and elimination can be a problem with solvent-free epoxy coatings, like System Three® SilverTip™ and Mirrorcoat®, especially when applying to porous surfaces like wood or concrete. The cause is typically due to either one of two things:

1) Air expanding within the substrate and releasing into the freshly applied epoxy, or

2) Air entrained in the mixed product during mixing and applying.

Suggestions to avoid trapping bubbles:

1. Apply the epoxy on a surface that is in the process of cooling down or at least at a stable temperature. If the material is being warmed by the sun or another heat source, air will expand and come out of the material forming bubbles in the epoxy coating.

2. On the bare substrate apply an initial, very thin coat to seal in any air pockets in the material. On a flat or broad surface, use a 1/8" nap foam roller and apply the epoxy at 1/2 fluid oz. per sq. ft. Some ultra-porous substrates may require a second coat to fully seal in air pockets. If bubbles still form, dragging a disposable bristle brush across the wet epoxy should remove them.

3. On irregular surfaces, use the bristle brush and brush out the coating just thinly enough to wet the surface. If any one epoxy coat is applied too thickly, the air pockets will expand and form bubbles which will become trapped in the epoxy.

4. Even with a fully sealed substrate, bubbles can persist in subsequently applied epoxy coats. These bubbles are the result of entrained air from mixing the material before application. Usually, these bubbles will pop by themselves before the product has gelled. Stubborn bubbles can be removed using a propane torch, waving it back and forth holding the flame 6-8" from the surface. Do not overdo the action with the torch as scorching of the epoxy can occur.
