ABSTRACT:
A hot melt moisture cure polyurethane adhesive composition includes at least one polyurethane prepolymer. The prepolymer includes the reaction product of a polyol component and a polyisocyanate component. The polyol component includes a) at least one amorphous polyester polyol comprising the reaction product of neopentyl glycol, hexanediol and at least one of phthalic anhydride and phthalic acid; b) at least one liquid polyester polyol having a viscosity of greater than about 10,000 cps at 80° C.; c) at least one crystalline polyester polyol having a melting point of from about 40° C. to about 120° C.; and d) at least one thermoplastic polyurethane.
