EnvironMolds Casting Resin - 1-Pint

Before you begin to cast a polyurethane mold, you must prepare the mold by applying the appropriate release agent. You should allow the release agent to dry approximately 10 minutes before you pour the casting. Please note that silicone molds do not require a release agent. If you want to use an in-mold paint, like CilCoat, you should apply it after the release agent dries. Using two clean, dry, plastic containers of equal size, measure equal amounts of the curative (part A) and the prepolymer (part B). If you want to use a filler or powder, use another clean, dry, plastic container to measure the filler or powder. Do not measure more it than you can pour within its 2 minutes pot life.

Use a plastic or metal utensil to mix it. Although it gels quickly, you should take your time to carefully pour it into the mold. Pour slowly so that any air bubbles that may have formed during mixing can break over the lip of the container as it pours out. Once you have poured your casting, do not disturb the mold or demold the casting for 815 minutes. Although you may work with your cast in as little as 15 minutes after demolding, we recommend that you allow your cast to cure for 30 minutes for best results.
