ABSTRACT:
An improved method for forming a protective coating on a plastic substrate is disclosed, comprising the application of a curable coating composition which contains at least one alkyltrialkoxysilane in a water/organic solvent dispersion of the colloidal silica onto the substrate, and then curing the composition at elevated temperatures with an effective amount of a tetrabutylammonium carboxylate catalyst such as tetra-n-butylammonium acetate. This invention also includes improved curable silicone coating compositions containing such a catalyst.
