Abstract
A coating composition containing a film-forming organosilane polymer, optionally a non-aqueous dispersed polymer, and a crosslinking agent selected from one or both of an organic polyisocyanate and melamine crosslinker. Fluorine functionalities are incorporated in the organosilane polymer to enhance soil resistance and cleanability. The coating composition can be used as a clearcoat over a conventional pigmented basecoat. The coating composition provides improved soil resistance and cleanability.
