Abstract
Binder compositions suitable for manufacturing foundry cores and moulds by the "no-bake" and "cold- box" process comprise a liquid polyisocyanate, a polyol component which comprises either an aromatic amine polyol or an adduct of ammonia and an alkylene oxide, and optionally a gaseous tertiary amine curing agent. Foundry cores and moulds for casting light-weight metals are prepared using a binder composition comprising a liquid polyisocyanate, an amine polyol, particularly one as defined above, and optionally a gaseous tertiary amine curing agent. The cores and moulds produced exhibit excellent shakeout properties.
