单组分湿固化型聚氨酯密封胶催化剂的研究

Investigation of catalysts in one component moisture curable polyurethane sealant

单组分湿固化型聚氨酯密封胶是一种发展前景很好的密封胶 ,而催化剂是影响其性能的重要因素之一。

One component moisture curable polyurethane sealant is considered as a promising sealant used in building and automobile. Among the compositions of the materials, catalyst plays one of the most important factors for the resulting materials. In this paper, the sort and activity of the catalysts are introduced. The influences of these catalysts on the bubble forming of the materials are also described.
