CA 1315037

Abstract of the Disclosure A one component, solventless, storage stable, low temperature, curable urethane composition comprising (1) a branched, blocked isocyanate prepolymer comprising the reaction product of a polyol having a functionality of at least 2, an aromatic polyisocyanate having a functionality of at least 2, the combined functionality of the polyol and the polyisocyanate being greater than 4 and a ketoxime blocker; (2) a polyol crosslinking agent containing at least two OH groups; (3) a deblocking and curing catalyst for (1); and (4) a dessicant. The composition on heating to 100-120°C results in a cured polyurethane within 10 - 30 minutes. The composition can also be combined with polymeric powder, e.g., polymethylmethacrylate to yield cured reactive plastisols. The aforesaid compositions are useful as sealants, coatings or adhesives.
