ABSTRACT:
The subject invention relates to a foundry binder system which cures in the presence of a volatile amine curing catalyst comprising (a) an epoxy resin,(b) an organic polyisocyanate, (c) a reactive unsaturated acrylic monomer or polymer, and (d) an oxidizing agent. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes which are used to make metal castings.
