Two-part Casting Resin

Two-part casting resins are plastic or elastomer compounds used to cast parts, molds or form a structure in place. They are available in the form of spray foams, "froth-packs", and A + B pourable foams. Two-part casting resins usually consist of two part (A+B) systems that are cast into open molds or forms. A multi-component system typically consists of two separate components (A + B) where A is the resin and B is the catalyst or hardener. The user or fabricator mixes the components to start the curing process. Two or multi-component adhesive or sealant systems consist of two or more resins or a resin and a hardener, crosslinker, activator or catalyst that when combined react and cure into a polyermized compound or bond. The two component systems are mixed and then applied.
