More Information
Summary:The present invention discloses catalyst compositions for producing polyurethane products having improved heat and humid aging properties and to processes for the manufacture of polyurethane products using such catalysts. The catalysts are based on a blend of at least one compound having a tertiary amine and isocyanate reactive group and at least one compound having a quaternary ammonium alkoxide moiety and at least one tertiary amine group wherein the later compound is partially or completely neutralized with at least one acidic compound.
