Abstract
Disclosed is a synergistic catalytic combination of 1,2-dimethylimidazole with tris(3-dimethylaminopropyl)amine and a salt of 1,8-diazabicyclo(5,4,0)undecene-7. The combination catalyst is useful in polyurethane systems such as elastomers, microcellular, rigid, semirigid, and flexible foams, such as integral skin semiflexible foams used in the manufacture of steering wheels.
