ADHESIVE COMPOSITION Russian patent published in 2015 - IPC C09J133/00 C09J133/10 C09J183/02 C09J183/05 

FIELD: chemistry.

SUBSTANCE: invention relates to polymer chemistry and specifically to adhesive compositions based on a copolymer of butyl methacrylate and methacrylic acid, used for bonding different substrates (metal, wood, ceramic etc.). The adhesive composition contains (pts.wt) 20.0-30.0 copolymer of 95 wt % butyl methacrylate with 5 wt % methacrylic acid (BMK-5); 3.0-10.0 organic silane of formula (C₂H₅O)_4-n-Si-[OSi(OC₂H₅)₃]_n, where n=0-2; 0.5-3.0 water; 2.0-10.0 aerosil and an organic solvent - 46.99-67.5.

EFFECT: use of the organic silane of given formula and water in the adhesive composition increases adhesive strength and heat resistance of the adhesive composition based on the BMK-5 copolymer.
