產品應用
胺催化劑33LV主要用作聚氨酯泡沫塑料的凝膠催化劑,廣泛用于軟質、半硬質、硬質聚氨酯泡沫塑料、涂料、彈性體,在聚氨酯發泡體系中,異氰酸酯首先和三乙烯二胺反應生成活性絡合物,絡合物的性質很不穩定,一旦氨基甲酸酯鍵生成后,它就會游離出來,有利于更進一步催化,三乙烯二胺對凝膠反應和發泡反應都有較強的催化作用,尤其對聚氨酯和羥基的催化作用選擇性更強。

Product use
Amine catalysts 33 lv mainly used for polyurethane foam gel catalyst, widely used in the soft, semi-hard, rigid polyurethane foam plastics, coatings, elastomers, in polyurethane foam system, isocyanate and first three ethylene diamine complex reaction activity, the nature of the complex is very unstable, once the carbamate key generation, it will be free to come out, is conducive to further catalytic, triethylene diamine on the gel and foam reaction has a strong catalytic effect, especially for the catalyst selectivity of polyurethane and hydroxyl.
