Abstract
A coating composition for forming an electrically insulating film, a method of making the coating composition, and the cured coating composition are provided. The coating composition includes a curable polymer comprising at least one functional group for forming cross-linking structures, a curative configured to react with the at least one functional group in the curable polymer, a sol comprising silica or metal oxide nanoparticles having a particle diameter in a range of from about 0.1 nm to about 100 nm, an organic titanate, and optionally at least one solvent or diluent. The resulting cured coating or paint provides good insulation, coverage, adhesion, toughness, and corrosion resistance.
