Methods for forming composite coatings on substrates |
摘要 |
The present invention provides methods for forming composite coatings on substrates including the steps of: (A) applying an aqueous primary coating composition to at least a portion of a surface of a substrate, the primary coating composition including: (1) at least one thermosettable dispersion including polymeric microparticles having functionality adapted to react with a crosslinking material, the microparticles including: (a) at least one acid functional reaction product of ethylenically unsaturated monomers; and (b) at least one hydrophobic polymer having a number average molecular weight of at least about 500; and (2) at least one crosslinking material, to form a substantially uncured primary coating thereon; (B) applying a secondary coating composition to at least a portion of the primary coating formed in step (A) without substantially curing the primary coating to form a substantially uncured secondary coating thereon; and (C) applying a clear coating composition to at least a portion of the secondary coating formed in step (B) without substantially curing the secondary coating to form a substantially uncured composite coating thereon.
