Abstract:

An improved process for applying a multi-component composite coating composition to a substrate is provided. The process includes the steps of roll applying to the substrate a colored film-forming composition to form a base coat and applying to said base coat at least one clear film-forming composition to form at least one transparent top coat over the base coat. At least one of the clear film-forming compositions contains an effect pigment. Additionally, an improved process for applying a multi-component composite coating composition to a metal substrate is provided. The process may include the following steps: a) optionally contacting the substrate surface with a pretreatment composition; b) optionally applying a primer coating composition to the substrate surface; c) curing the primer coating composition if applied; d) roll applying to the substrate a colored film-forming composition to form a base coat; e) curing the base coat; f) applying to at least a portion of said base coat at least one clear film-forming composition to form at least one transparent top coat over the base coat; and g) curing the at least one clear coat. At least one of the clear film-forming compositions contains an effect pigment. Substrates treated by the process of the present invention are suitable for use in the manufacturing of automotive parts, having automotive quality appearance.
