COMPOSITION FOR COATINGS Russian patent published in 2014 - IPC C09D109/00 C09D175/14 

FIELD: chemistry.

SUBSTANCE: composition for coatings contains low-molecular hydroxyl-containing butadiene rubber PDI-1K, polyisocyanate based on 4,4′-diphenylmethanediisocyanate, glycerol, a catalyst of urethane-formation - tin dibutyldilaurinate. As rubber, used is a product of copolymerisation of 100 wt.p. of low-molecular hydroxyl-containing rubber PDI-1K with 20-40 wt.p. of styrol, preliminarily obtained in a medium of lamp oil in the presence of a peroxide initiator.

EFFECT: increased level of strength properties, first of all the coating strength.
