Abstract:
An isocyanate reactive composition for making a polyurethane foam includes a tertiary amine urethane catalyst comprising a di(C1-C4)alkyl fatty alkyl amine and a polyester polyol. The use of one or more of fatty alkyl tertiary amine serves to reduce hydrolysis of the polyester polyol in the isocyanate reactive composition.
