Hydroxyl containing quaternary ammonium salts of fatty acids as internal mold release compositions

摘要

In an active hydrogen-containing B-side composition for reaction with a polyisocyanate-containing A-side composition to make a polyurethane or polyurethane/urea elastomer by reaction injected molding, the improvement which comprises a mold release composition which is the reaction product of a C12-C36 fatty acid, a tertiary amine having at least one C12-C18 alkyl substituent and a C2-C21 reactive epoxide.
