Beschreibung
Zusammenfassung:	A moisture-curable polyurethane hot-melt adhesive which contains a urethane prepolymer that is obtained by reacting a polyisocyanate component that contains at least a modified aliphatic diisocyanate with a polyol component and that has an isocyanate group at a terminal, the average number of functional groups of isocyanate groups in the polyisocyanate component is 2.0-3.0, and the polyol component contains a trifunctional or higher polyfunctional polyol in an amount of 1-8 mass% of the polyol. 湿气固化型聚氨酯热熔粘接剂，其含有氨基甲酸酯预聚物，所述氨基甲酸酯预聚物由至少含有脂族二异氰酸酯改性物的多异氰酸酯成分和多元醇成分的反应得到，在末端具有异氰酸酯基，其中，所述多异氰酸酯成分中的异氰酸酯基的平均官能团数为2.0～3.0个，所述多元醇成分含有在所述多元醇中1～8质量％的三官能以上的多官能多元醇。
