2017-2-17 16:57:27
Curing agent varieties for curing content on the mechanical properties, heat resistance, water resistance, corrosion resistance and so on have very big effect, such as the heavy aromatic amine, imidazole, acid anhydride curing agent heat resistance of cured epoxy resin was higher than aliphatic amine, low molecular polyamide curing agent; Aromatic acid anhydride curable epoxy resin's water resistance is better than that of aromatic diamine and aliphatic amine curing agent; Sanya ethyl four amine curing agent good alkali resistance, but poor resistance to acid and formaldehyde solution resistance. More than alicyclic amines (such as isophorone diamine) drug resistance of cured epoxy resin is good. Anhydride curing agent of epoxy resin curing alkali resistance is better than that of acid resistance. According to different purposes and performance requirements choose proper curing agent varieties.
