RIM polyol blends containing acidic siloxane internal mold release

The invention consists of a composition containing a chemically blocked trimerization catalyst and a polyurethane prepolymer resin or resins with reactive isocyanate groups. In the absence of heat, the catalyst is not active and the solution of catalyst in the resin undergoes no appreciable reaction for periods ranging from hours to weeks depending upon the composition and concentration of the catalysts and the structure and concentration of the isocyanate groups. When heat is applied to the mixture a trimerization reaction occurs which produces a crosslinked polyurethane network with utility as an elastomer or as an adhesive.
