Abstract
Composition for effectively sealing the surface of a substrate from penetration by solvents commonly used in automotive primer, paint and paint thinners. The coating composition is particularly useful for providing a sealed surface for priming and topcoating reaction injected molded urethane, reinforced reaction injection molded urethane, and other substrates which are sensitive to the organic solvents normally present in automotive primer and paint. The composition for sealing the surface of the substrate comprises a urethane polymer, water, and a monohydric alcohol having less than seven carbon atoms.
