摘要 |
In one embodiment, the invention is an composition comprising: a) one or more isocyanate functional polyether polyurethane prepolymers; and b) one or more prepolymers of one or more polyisocyanates and one or more polyesters wherein the terminal groups on the polyester polyol polyurethane prepolymer are the residue of a monofunctional polyalkylene glycol (hereinafter capped polyester polyurethane prepolymer) or one or more polyester polyols which are capped with the residue of one or more monofunctional isocyanates (hereinafter isocyanate capped polyesters); wherein the composition is a low viscous paste at temperature of from about 40 to about 80° C. and is high viscous paste at a temperature of from about 40° C. or less. In a preferred embodiment the composition further comprises c) one or more catalysts for the reaction of isocyanate moieties with hydroxyl groups. In another embodiment the invention is a method of bonding two or more substrates together which comprise contacting the two or more substrates together with a composition according to this invention disposed along at least a portion of the area wherein the substrates are in contact wherein the composition is a low viscous paste. In a preferred embodiment the composition is heated to about 40° C. to about 80° C. and converted to a low viscous paste prior to contacting it with the one or more substrates.
