敬请咨询3M专家

结构胶的强度与热熔胶的粘合速度

  • 反应型聚氨酯胶粘剂(PUR胶粘剂;亦称为反应型热熔胶、反应型聚氨酯或者RPU胶粘剂)是单组分剂型,具有热熔胶的初始粘合速度和结构胶的粘合强度。粘合分两个阶段形成:在胶粘剂冷却并固化为热熔胶状,达到持粘强度,然后在接下来的24-48小时湿固化反应持续,达到最终的结构强度。 这些胶粘剂能够承受极端温度,灵活地抗振动和抗冲击性。

    3M™ Scotch-Weld™ PUR胶粘剂的开放时间范围广,可以根据具体工艺调整,挥发性有机化合物(VOC)含量低,甚至不含挥发性有机化合物。 这些胶粘剂能很好地粘接金属、玻璃、陶瓷、木材以及聚苯乙烯和聚丙烯酸等塑料。 PUR胶粘剂的快速操作强度和高最终强度,结合无需混合的单组分产品的优点,使其成为了提高生产量和缩短加工时间的出色产品之选。
