ABSTRACT:
A moisture curable hot melt composition comprises:
(a) a first isocyanate-terminated polyurethane prepolymer that is the reaction product of a crystalline polyester polyol and a polyisocyanate;
(b) a crystalline, reactive wax; and
(c) optionally, a second isocyanate-terminated polyurethane prepolymer that is the reaction product of a polyisocyanate and a hydroxy-functional polymer that is different than the crystalline polyester polyol.
