FIELD: medicine, pharmaceutics.
SUBSTANCE: invention relates to coating composition, applied, for instance, as transparent coatings, base coatings, pigmented coating layers, used, prime coatings, etc. Composition contains polyisocyanate, polyol, metal-based catalyst for carrying out reaction of addition reaction between isocyanate groups and hydroxyl groups, thiol-functioning compound and carboxylic acid, carbonyl group of carboxylic acid being in connection with π-electronic system.
EFFECT: creation of novel coating composition, demonstrating presence of favourable property balance, namely, low level of volatile organic solvent content with operation viscosity, high rate of hardening and long viability, which results in obtaining coatings, which demonstrate good outlook characteristics, in particular, low liability to formation of pinholes, and good hardness.
