Title:
COATING COMPOSITIONS HAVING IMPROVED SCRATCH RESISTANCE, COATED SUBSTRATES AND METHODS RELATED THERETO
Document Type and Number:
WIPO Patent Application WO2001009259
Kind Code:
A9
Abstract:
Coating compositions are provided which are formed from components comprising (a) at least one polysiloxane comprising at least one reactive functional group; (b) at least one reactant comprising at least one functional group that is reactive with at least one functional group selected from the at least one reactive functional group of the at least one polysiloxane and at least one functional group of at least one reactant; and (c) a plurality of particles, wherein each component is different, and wherein the at least one reactive functional group of the at least one polysiloxane and the at least one reactive functional group of the at least one reactant are substantially nonreactive with the particles. A multi-component composite coating composition formed from a basecoat and a topcoat deposited from the curable coating composition also is provided. The multi-component composite coating compositions of the invention provide highly scratch resistant color-plus-clearcoatings capable of retaining scratch resistance after weathering.
