ABSTRACT:
Polyurethane coating compositions having improved application characteristics as well as other desirable properties are prepared by adding insoluble crosslinked acrylic polymer microparticles to solutions comprising an ungelled hydroxyl-containing urethane reaction product. The compositions may be spray coated onto various substrates in two coat applications to form coatings having improved film build, pattern control and flow control while maintaining the gloss characteristics of the film. These coatings are useful in general coating applications and are particularly useful on resilient and rubbery substrates such as foams or extruded rubber.
