Storage Information

Qiguang Group recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products' performance in the end use. The optimum storage temperature is between 10 °C and 30° C. Lower and higher storage temperatures are not preferable and should be avoided.

System of law
There are various synthetic routes for N,N-dimethylcyclohexylamine, and depending on the type of the raw material, there are a cyclohexanone method, an N,N-dimethylcyclohexylamine method, a cyclohexylamine method, and a phenol method.

特殊用途 N，N-二甲基环己胺的主要用途
是作为硬质聚氨酯泡沫的催化剂。它是一种低粘度、中等活性胺催化剂，用于冰箱、片材、喷雾剂和原位填充聚氨酯硬质泡沫。该催化剂同时催化凝胶化和发泡 ，为硬质泡沫的发泡反应和凝胶反应提供了相对平衡的催化性能，对水和异氰酸酯的反应（发泡反应）具有更强的催化剂，多元醇羽流异氰酸酯的反应也具有中 等催化作用，是发泡反应的强初始催化剂。除用于硬质泡沫外，还可用于软质泡沫、半硬质泡沫等辅助发泡剂的成型。成分性能稳定，可调节性强，可长期储存 。
