Appl. No.:

6/290984

Inventors:

Daniel R. Olson - Schenectady NY

Assignee:

General Electric Company - Schenectady NY

International Classification:

B32B 516
B32B 2730

US Classification:

428331

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.
