ADHESIVE COMPOSITION BASED ON COLD-CURED EPOXY RESIN MODIFIED WITH POLYURETHANE FOR FIXING TWO-LAYER COATINGS MADE OF POLYISOPRENE RUBBER Russian patent published in 2023 - IPC C09J163/02 C09J11/02 C09J11/08 

FIELD: industrial and civil engineering.

SUBSTANCE: adhesive composition is proposed, which includes an elasticized diglycidyl ether of bisphenol-A/F with an epoxy equivalent of 374-416 g/mol (30.0-32.0 wt.pts.), a mineral filler (53.0-55.0 wt.pts.), a dispersant (0.5-0.6 wt.pts.), a rheological additive (0.5-0.7 wt.pts.), pigment (0.5-0.9 wt.pts.), hardener based on modified cycloaliphatic polyamine (9.9-10.5 wt.pts.) and solvent (1.5-2.3 wt.pts.).

EFFECT: invention enables to produce an adhesive material that allows the sports coating to be securely attached to concrete and asphalt surfaces, as well as to obtain an adhesive layer that retains flexibility at temperatures up to -30°C, which allows the composition to be used at sports facilities operated in winter.
