A moisture curable polyurethane adhesive composition comprises an aromatic polyisocyanate, a polyester polyol, a functionally effective amount of a plasticiser, and an optional polyether polyol. The aromatic polyisocyanate has an isocyanate functionality that does not exceed about 2.3. The polyester polyol may be derived from the reaction of adipic acid and a diol (e.g., neopentyl glycol, diethylene glycol, 2-methyl-1,3-propane diol, 2,3-methylbutane diol, or 1,2-propylene diol) or it may be provided by a polycaprolactone diol. The adhesive compositions are particularly useful in bonding vinyl to wood.
一种湿气固化聚氨酯粘合剂组合物由芳香族多异氰酸酯、聚酯多元醇、功能有效量的增塑剂和任选的聚醚多元醇组成。芳香族多异氰酸酯的异氰酸酯官能度不超过约 2.3。聚酯多元醇可由己二酸和二元醇(如新戊二醇、二甘醇、2-甲基-1,3-丙二醇、2,3-甲基丁二醇或 1,2-丙二醇)反应生成,也可由聚己内酯二元醇提供。这种粘合剂组合物尤其适用于将乙烯基粘合到木材上。
