Polyurethane-forming binders |
摘要 |
This invention relates to a polyurethane-forming no-bake foundry binder comprising a (a) polyether polyol component comprising (1) a polyether polyol, (2) hydrofluoric acid, and (3) an aminoalkoxysilane, (b) a polyisocyanate component, (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.
