Method for forming a boundary layer between two layers via catalyzed reaction of components from both layers
Abstract:
A wet on wet coating application method. The method includes contacting a polyol-containing layer including a polyol in an amount of 10 to 70 percent by weight and a isocyanate-catalyst-containing layer including an isocyanate and a catalyst to form a boundary layer between the layers being the reaction product of the polyol and isocyanate catalyzed by the catalyst and carried out at 68° F. to 75° F.
