摘要：
This invention relates to foundry mixes and their uses. The foundry mixes comprise (a) a foundry aggregate, and (b) a foundry binder comprising in admixture; (1) an acetoacetate ester; (2) an .alpha., .beta. ethylenically unsaturated monomer; and (3) a liquid tertiary amine catalyst having a pK value of 12-14. The foundry mixes are used to prepare foundry shapes made from foundry mixes by a no-bake process.
