    摘要: A composite plastic structure is described. The composite structure includes: (a) a shaped polycarbonate article having an edge region, the edge region having an adhesion-promoting geometric feature therein; (b) a coating applied to the surface of the shaped polycarbonate article; and (c) a polymer that is injection-molded or cast over the edge region of the shaped polycarbonate article. The polymer (c) envelopes the adhesion-promoting geometric feature of the shaped polycarbonate article (a). The envelopment of the adhesion-promoting geometric feature by the polymer (c) provides a structurally firm connection between the shaped polycarbonate article (a) and the polymer (c). Also described is a method of preparing the composite structure, and composite structures according to the present invention, such as picture frames, slide frames, windows having a seal or frame, and a glazing for a motor vehicle.

    摘要: A UV-stabilizer comprising a mixture of hydroxybenzotriazole and a hydrolyzable silane containing at least one epoxy group is disclosed. The stabilizer is especially suitable as a component of a siloxane system for coating substrates, especially thermoplastic substrates and most especially polycarbonate substrates.
