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. This catalysis results in greater reactivity at the surface between reacting portions and lower delamination of the surface of the foam, thereby leading to more attractive skins with a more consistent cell structure, and lower de-mold times due to skins whose nature makes them less likely to adhere to the surface of the mold. These foams will be less likely to tear upon opening of the mold, and production quality and output will be improved.
