Abstract: The present invention relates to a resin-coated powder material prepared by coating at least one organic resin selected from a silicone resin and a fluorocarbon resin; a coating composition prepared by mixing a zinc oxide needle-like single-crystal inorganic powder with a silicone resin coating composition and/or fluorocarbon resin coating composition; and a substrate surface-modifying method which comprises coating an inorganic powder dispersion containing, as essential components, a needle-like single-crystal inorganic powder and a resin onto a plastics substrate or inorganic substrate to impart water-repellency to the surface of the substrate.

Abstract: There is disclosed a process to form metallic multilayer coating films characterized by coating on the uncured coating surface of a paint formed on a substrate with a composition (B), which contains non-leafing aluminum flake and organic solvent and then by coating, optionally after coating with a topcoat paint (C), with a clear paint (D). According to said process metallic multilayer coating films, which is white, excellent in metallic luster impression and having a high flip-flop effect, can be formed by using non-leafing aluminum flake pigment.

Abstract: There is disclosed a novel organic solvent type coating composition capable of making the solid content concentration at the time of coating to higher than 70% by weight, without lowering the properties, which urethane type coating materials have, such as acid resistance, scratch resistance, finishing appearance etc. The composition comprises (A) a vinyl type polymer having both hydroxyl groups and alkoxysilyl groups in the molecule and having a number-average molecular weight in a range of 2,000 to 10,000; (B) a polyol compound having a number-average molecular weight of less than 1,000 and having a hydroxyl value in a range of 120 to 1,000 mgKOH/g; (C) a polyisocyanate compound having a number-average molecular weight of less than 2,000; and (D) a silanol group forming catalyst.

Abstract: An organic solvent-based heat-curable high solid coating composition comprising:(A) a carboxyl-containing compound having an acid value of 50 to 500 mg KOH/g wherein 20 mol % or more of the carboxyl groups are silylated carboxyl groups,(B) at least one epoxide selected from (B-1) an epoxy-, hydroxyl- and hydrolyzable alkoxysilyl-containing vinyl polymer, (B-2) the vinyl polymer (B-1) wherein 20 mol % or more of the hydroxyl groups are silylated hydroxyl groups, and (B-3) an epoxy compound having a number average molecular weight less than 1,000, and(C) a crosslinked particulate polymer,the composition having a solid content of 65 wt. % or more; and a method for forming a topcoat using the composition. The composition of the invention has a sufficiently high solid content, is capable of forming a coating film with high resistance to acids and the like, and is excellent in low-temperature curability, storage stability and recoat adhesion.
