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 improved. The products of this invention are useful in all types of automotive and industrial paint applications.
