ABSTRACT:
This invention relates to a solventless polyurethane no-bake foundry binder system comprising, as individual components (a) a polyol component comprising a polyether polyol, glycol, and an aromatic polyester polyol, (b) an organic polyisocyanate component, and (c) a liquid tertiary amine catalyst component. Foundry mixes are prepared by mixing the binder system with a foundry aggregate by a no-bake process. The resulting foundry shapes are used to cast metal parts from ferrous and non-ferrous metals.
