ABSTRACT:
A process for preparing a coating composition includes contacting a polyol, a silsesquioxane, a polyurethane dendrimer, and a crosslinker, wherein the polyol, the silsesquioxane, the polyurethane dendrimer, and the crosslinker are dispersed within a solvent and forming a self-stratifying coating. Further, a coating composition includes a polyol, a silsesquioxane, a polyurethane dendrimer and a crosslinker forming a mixture dispersed within a solvent.
