1. A polyurethane comprising a reaction product of components comprising:
(a) an isocyanate functional urethane prepolymer comprising a reaction product of components comprising:
(i) about 1 equivalent of at least one polyisocyanate; and(ii) about 0.01 to about 0.5 equivalent of at least one polyol having at least 3 hydroxyl groups, based upon the about 1 equivalent of the at least one polyisocyanate; and (b) about 0.1 to about 1.0 equivalent of at least one polyol having at least 3 hydroxyl groups, based upon the about 1 equivalent of the at least one polyisocyanate,wherein the at least one polyol (ii) can be the same or different from the at least one polyol (b). |
