Title:
POWDER COATING PRECURSORS AND THE USE THEREOF IN POWDER COATING COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO2005007757
Kind Code:
A3
Abstract:
A laminar pigment which has hydrolyzed silane coupling agent treated surface is used as a pigment for a powder coating composition. By combining the pigment with a powdery film-forming polymer, a film-forming composition, which can be applied by electrostatic coating, is produced. With the addition of leveling agent to the silane treated products, the spray properties of effect pigments are intensified. The products of this invention are useful in all types of automotive and industrial paint applications.
