POLYURETHANE COATING COMPOSITION Russian patent published in 2010 - IPC C08L75/04 C08K3/32 C08K5/53 C08K5/103 C08G18/10 C09D175/04 C09K21/12

Abstract RU 2391362 C2

FIELD: chemistry.

SUBSTANCE: invention relates to polyurethane composition used as a protective coating. The composition contains the following in pts. wt: 770 - polytetramethylene etherglycol with molecular weight of 1950, 200 - 4,4'-diphenylmethanediisocyanate, 80-100 - dimethylformamide, 36 - hydroxyl-containing compound, 100-120 - methylphosphite borate and 15-18 - glycidalmethacrylate. A prepolymer is synthesised first as an initial component by reacting polytetramethylene etherglycol and 4,4'-diphenylmethanediisocyanate in molar ratio OH:NCO-groups equal to 1:2.

EFFECT: composition has better complex properties, specifically high fire- and heat resistance and good physical and mechanical properties, eg high strength and extensibility.
