POLYURETHANE COMPOSITION Russian patent published in 2008 - IPC C08L75/04 C09D175/04 C08K3/36 

FIELD: chemistry.

SUBSTANCE: invention concerns quickly solidifying polyurethane-based polymer compositions with enhanced adhesion to metal surfaces and can be applied in production of protective coatings, sealing glues, mastics, particularly for sealing of perforated holes in paper-making machines. Composition includes polyfurite urethane forpolymer, liquid solidifier based on 3,3'-dichlor-4,4'-diaminodiphenylmethane and polyoxytetramethyleneglycol with molecular weight of 1000 at mol ratio of 0.95:0.1, aerosil, and additionally contains glycidylmetacrylate as adhesion additive, and can include di-(2-ethylhexyl)phthalate as plastifyer.

EFFECT: obtaining composition with high adhesion to metal surfaces and improved thixotropy without impairing high physical and mechanical characteristics level.
