BINDING SUBSTANCES HAVING HIGH HYDROXYL NUMBER AND TRANSPARENT LACQUER COMPOSITIONS CONTAINING SAID SUBSTANCES, HAVING GOOD OPTICAL PROPERTIES AND GOOD SCRATCH RESISTANCE AND CHEMICAL RESISTANCE Russian patent published in 2013 - IPC C08G63/02 C08G63/20 C08G63/91 C08G18/42 C09D201/00 C09D167/00

Abstract RU 2480484 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a hydroxy-functional binding substance having a hydroxyl number ≥180, determined according to DIN 53240, and a solubility parameter SP ≤10. The present invention also relates to methods of producing said binding substance, a transparent lacquer composition containing said substance and to a substrate coated with such a transparent lacquer composition.

EFFECT: obtaining binding substances for transparent lacquer compositions having high content of solid substances, which lead to formation of coatings with high scratch resistance, chemical resistance and good optical properties.
