降低湿固化聚氨酯弹性体涂层气泡的技术途径

Technical Route to Reduce the Blister in High-solid Mois-ture-cured PU Elastomer Coatings Film

评述了降低高固体分聚氨酯湿固化弹性涂层气泡的常用技术途径,提出应用硅氧烷封端技术制备聚氨酯弹性体,得到光洁无泡的并具有一定机械性能的厚涂聚氨酯弹性材料。

This article narrates general technical routes to re- duce blisters in high-solid moisture-cured polyurethane coat- ings film; and tells the preparation of PU elastomer with sili- cone blocking technology to give elastic glossy PU material with thick-film, no-blister and good mechanic property.
