Abstract
The present invention provides a binder composition which is rapidly self-curing at ambient temperatures and which comprises (A) a polyol component including at least one aromatic tertiary amino polyol, (B) an isocyanate component having a functionality of two or more and (C) sufficient solvent to reduce the viscosity of the composition to below about 1000 centipoises, said aromatic tertiary amino polyol being present in said composition in an amount to provide at least sufficient tertiary amine 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 a binder which is the reaction product of components (A) and (B) and foundry cores or molds made therefrom and including the process for their manufacture from the moldable compositions.
