COATING COMPOSITION, INCLUDING POLYISOCYANATE AND POLYOL Russian patent published in 2014 - IPC C08G18/10 C08G18/22 C08G18/38 C08G18/40 C09D175/04

Abstract RU 2510973 C2

FIELD: chemistry.

SUBSTANCE: claimed invention relates to versions of non-water coating composition, in fact consisting of: (a) polyisocyanate, (b) polyol, with average functionality more than 3 hydroxyl groups per molecule, (c) metal-based solidification catalyst for reaction of binding isocyanate groups and hydroxyl groups, (d) mercaptocarboxylic acid and (e) volatile organic solvent, and coating composition does not contain carboxylic acid, in which carbonyl group of carboxylic acid is in conjugation with p-electron system. Also described are set of components for preparation of claimed coating composition, its application and method of coating application on substrate with use of said composition.

EFFECT: creation of coating composition, which has low content of volatile organic solvent, high rate of solidification and long storage time, which result in obtaining coating with good external properties, in particular low predisposition to formation of craters, high strength, flexibility, scratch resistance, luster, resistance to external factors and resistance to chemical substances and ultraviolet radiation.
