The variety of curing agents has a great impact on the mechanical properties, heat resistance, water resistance, corrosion resistance of curing agent such as aromatic polyamine, imidazole, anhydride curing agent epoxy resin heat resistance is higher than aliphatic polyamine, low molecular polyamide curing agent: The water-resistance of aromatic anhydride cured epoxy resin is better than that of chromatic diamine and aliphatic polyamine curing agent.
· Sanya ethyl tetraamine curing agent has good alkali-resistance, but poor acid resistance and formaldehyde resistance.
· Alicyclic polyamines (such as isophorone diamine) cured epoxy resin has good drug resistance.
· The alkali resistance of the epoxy resin cured by an anhydride curing agent is better than acid resistance
