ABSTRACT:
Novel resin binders for foundry sand molds and cores are provided by reacting a polyol component comprising a phenol ketone resin, a reactive solvent and a cross-linking agent in a solution for these components with a solution of an organic polyisocyanate. The foundry binder cures rapidly at ambient temperature in the presence of a tertiary amine curing agent to provide strong foundry molds and cores. Polyether polyols may also be incorporated in the polyol component of the novel resin binder.
