Abstract

A coating composition, particularly a clearcoat composition, which may be a two-component clearcoat composition, comprises a film-forming material, a crosslinking agent, and a nonlinear polysiloxane polymer having a functional group reactive with the crosslinking agent. The coating composition exhibits excellent scratch resistance and adhesion of repair coating layers and sealants, such as windshield sealants.
