Abstract

A one component polyurethane precursor suitable as an in-mold coating composition composed of a prepolymer of an organic polyisocyanate with a polyol of a polyether polyol of 2 and 3 hydroxyl groups or a polyester polyol of 2 and 3 hydroxyl groups to give a free NCO content of about 3 to about 15% with a salt complex of a diamine, such as NaCl complex of MDA. The amount of filler and plasticizer, viz, those preferably of the crown or pseudocrown ethers preferably are adjusted to give the precursors a viscosity of about 5 to about 50 pascal seconds at the temperature the precursors are applied, but usually less than about 80.degree. C. These precursors are spread, applied or preferably injected onto the surface of the fiberglass molding viz a polyester or epoxy resin one and pressed at a pressure of about 5 to 200 psi (34,475 to 1,379,000 pascals) and higher at a temperature of at least 80.degree. C. to cure the precursor to give a polyurethane coating on the fiberglass molding.
