COATING COMPOSITION Russian patent published in 2015 - IPC C09D175/00 

FIELD: chemistry.

SUBSTANCE: coating composition includes low-molecular hydroxyl-containing butadiene-based caoutchouc, a plasticiser, filler, an isocyanate hardener - polyisocyanate, a three-functional low molecular alcohol and a catalyst of urethane formation. As the caoutchouc it contains hydroxyl-containing polybutadiene caoutchouc or caoutchouc-copolymer of isoprene and butadiene. Additionally it contains an acrylate-containing cross-linking agent, selected from the line of methylmethacrylate, butylmethacrylate, dimethacrylic ether of triethyleneglycol and oligoetheracrylate MGF-9, a peroxide initiator and N,N,4-trimethylaniline.

EFFECT: increased hardness and strength of elastomers for coatings.
