Abstract: Disclosed is a method of surface coating pigment particles, comprising treating uncoated titanium dioxide particles with a reaction product of a silicon oxide with an alkaline earth metal salt to form a coating comprising an oxide of silicon and the alkaline earth metal. The particles may also be treated with aluminum compounds to produce an aluminum oxide in the coating.

Abstract: A cationic electrodepositable coating composition is disclosed. The present invention in directed to a cationic electrodepositable coating composition comprising a lignin-containing cationic salt resin, that comprises (A) the reaction product of: lignin, an amine, and a carbonyl compound; (B) the reaction product of lignin, epichlorohydrin, and an amine; or (C) combinations thereof.

Abstract: A cationic electrodepositable coating composition is disclosed.

Abstract: A coating composition, comprising a film-forming component, a radiation curable group, and a matting agent, wherein, when the composition is deposited and treated to form a cured coating, the cured coating is characterized as having a higher concentration of the matting agent in a top half of the coating relative to a bottom half of the coating. Methods of treating a liquid radiation curable coating composition on a substrate are also disclosed, comprising applying an IR treatment to the liquid radiation curable coating composition, and applying a radiation curable treatment to the liquid radiation curable coating composition. The coating composition can provide improved properties, such as improved gloss, haze, flexibility, and/or chip resistance, when incorporated into a coating, or allow the use of less matting agent when compared to conventional coating compositions.

Abstract: An abrasion resistant coating composition is disclosed. The coating composition comprises a unique blend of particles, including alumina that has been treated with an organosilane and silica that is either similarly treated or left untreated. The use of these particles in combination allows for a significant reduction in the weight percent of wear resistant particles that can impart a suitable level of abrasion resistance to a coating. The particles can be included, for example, in a urethane acrylate binder that can be cured using UV radiation. Methods for using these coatings are also disclosed.
