Abstract: Methods and combinations of a curing catalyst with a mold release mixture, which is then subsequently applied to the surface of a mold prior to the application of polyurethane reactants to said mold, where the curing catalyst component has the effect of catalyzing the reaction at the surface of the molded part.

These foams will be less likely to tear upon opening of the mold, and production quality and output will be improved.
