Abstract

A method is provided for making abrasion resistant, non-opaque thermoplastic articles, for example, silicone-coated polycarbonate sheet useful as glazing material. A mixture of a certain UV absorber, for example a cyanoacrylate, and light stabilizer, such as a piperidine derivative, has been found to impart improved weathering resistance to the silicon-coated thermoplastic articles when used as part of an acrylic primer coating between the silicone top coat and the thermoplastic substrate.
