Foundry mixes containing a polyether polyol and their use |
摘要 |
This invention relates to foundry mixes which comprise a dry foundry aggregate and a polyurethane-forming foundry binder. The binder components include a polyether polyol component and an organic polyisocyanate component which is cured with a liquid tertiary amine catalyst. The foundry mixes are used to prepare foundry shapes made from foundry mixes by a no-bake process. The resulting foundry shapes are used to cast metal parts from ferrous and non ferrous metals.
