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.

Claim (Index 1):
A method of producing polyurethane articles comprising:\n coating a surface of a mold with a mold release mixture comprising a barrier release coating and 0.01% to 99.9% by weight of a curing catalyst, where the curing catalyst is selected from the group consisting of amides; carbamide; a metal catalyst comprising soaps, alcoholates or salts of metals having the formula:\n Me(Or\u2032) m X n-m \n where Me is a metal having an atomic number in the range of 21 to 83, R\u2032 is selected from the group consisting of aliphatic, cycloaliphatic, and aryl hydrocarbon radicals containing at least six carbon atoms, n is the valence of the metal Me selected and is at least 3, X is an organic carboxylic acid radical and m is a positive integer selected from the range of 0 to the valence of the metal Me, such that the metal catalyst catalyzes the chemical reaction between polyisocyanate and polyester with accompanying foaming of said composition, and combinations thereof; coating the surface of the mold with a curing catalyst mixture comprising a curing catalyst; drying the mold release mixture on the mold surface; drying the curing catalyst mixture on the mold surface; introducing polyurethane reactants to the mold; removing a polyurethane article from the mold; and recoating the mold surface with mold release mixture.
