REACTIVE HOT MELT ADHESIVE OBTAINED BY REACTING POLYETHER POLYOL, AMORPHOUS POLYESTER POLYOL AND A POLYISOCYANATE COMPOUND

摘要

PURPOSE: A reactive hot melt adhesive is provided to maintain excellent initial adhesion property while ensuring excellent hardness after curing.;CONSTITUTION: A reactive hot melt adhesive is obtained by reacting (A) polyether polyol, (B) amorphous polyester polyol with less than 40 °C of softening point, (C) amorphous polyester polyol with more than 40 °C of softening point, and (D) polyisocyanate compound. The reactive hot melt adhesive is prepared by reacting the amorphous polyester polyol(B) and amorphous polyester polyol(C) with a reaction product obtained by reacting polyether polyol(A) with polyisocyanate compound(D).;COPYRIGHT KIPO 2011
