Abstract

There are provided binder compositions particularly useful in the foundry art which are rapid curing and which comprise (A) a phenolic resin component including at least one resole or novolak resin, solvent comprising a mixture of (1) hydrocarbon solvent and (2) polar organic solvent containing at least sufficient organic phosphate and/or carbonate ester to increase the curing speed and solubility of the phenolic resin component, (B) an isocyanate component having a functionality of two or more and (C) sufficient catalyst to catalyze substantially completely the reaction between components (A) and (B). There is also provided a moldable composition comprising aggregate material, such as foundry sand, and such binder compositions and foundry cores or molds made therefrom and including a process for their manufacture from the moldable compositions by either "cold box" or "no-bake" procedures.
