摘要
The reaction of an organic polyisocyanate with an organic compound containing at least 2 active hydrogen containing groups is catalyzed with a synergistic co-catalyst combination of at least one organo-mercuric catalyst and at least one zinc salt of an alkylcarboxylic acid having about 2 to about 22 carbon atoms. Useful solid (non-cellular) and foamed polyurethane products are obtained which are produced at a faster curing rate than with use of either co-catalyst alone.
