Abstract:

Multi-component composite coating compositions are provided which comprise a base coat deposited from a pigmented film-forming composition and a transparent top coat applied over the base coat in which the transparent top coat is deposited from a film-forming composition comprising one ore more ungelled chain-extended organic polysiloxanes having reactive functional groups, and one or more curing agents having functional groups reactive with the functional groups of the polysiloxane. Additionally provided is a process for applying the multi-component composite coatings described above to a substrate. Substrates coated with the above-described multi-component composite coating compositions are also provided.
