ABSTRACT:
A blend of isocyanate-terminated polyurethane prepolymers comprising: (a) a first prepolymer which comprises the reaction product of an at least essentially semicrystalline hydroxy-functional material and a polyisocyanate; (b) a second prepolymer which comprises the reaction product of a poly(tetramethylene glycol)ether and a polyisocyanate; and (c) a third prepolymer which comprises the reaction product of an essentially amorphous hydroxy-functional material and a polyisocyanate. The blend may also include a fourth prepolymer which comprises the reaction product of a slightly branched hydroxy-functional material and a polyisocyanate.
