COATING COMPOSITION Russian patent published in 2015 - IPC C09D109/00 

FIELD: chemistry.

SUBSTANCE: coating composition includes low-molecular weight hydroxyl-containing butadiene-based rubber, an isocyanate curing agent - polyisocyanate, trifunctional low-molecular weight alcohol and a urethane-forming catalyst. The rubber is hydroxyl-containing polybutadiene rubber or isoprene and butadiene copolymer rubber. The composition additionally contains an acrylate-containing cross-linking agent selected from: methyl methacrylate, butyl methacrylate, dimethacrylic ester of triethylene glycol and oligoester acrylate MGF-9, a peroxide initiator and N,N,4-trimethylaniline.

EFFECT: high hardness and strength of coating elastomers.
