ABSTRACT:
A coating system especially useful on transparent plastic substrates is provided which includes: (1) an initial primer coat of polymethylmethacrylate in a solution of ethylene glycol monoethyl ether and diacetone alcohol, containing a small amount of an ultraviolet light absorbing compound, or a combination of an ultraviolet light absorbing compound and an ultraviolet radiation stabilizing agent, and (2) a secondary coat of a silicone resin coating composition. Such a coating system has a longer service life and improved resistance to delamination and discoloring compared to silicone resin coatings used with unmodified primers or coatings where ultraviolet light absorbers are added to the resin component only. Moreover, modification of the primer according to the invention will not significantly decrease the desirable adhesion properties, abrasion-resistance and optical clarity fo silicone resin coating compositions.
