1. Several curing agents are used in combination
A combination of several curing agents can be used to achieve synergistic effects, such as low molecular weight polyamide curing agent with a small amount of m-phenylenediamine curing agent, which can cure at room temperature and increase the toughness of the cured product while appropriately improving heat resistance. Sex. Triamellitic anhydride (TMA) is used in combination with methyltetrahydrophthalic anhydride. The eutectic mixture has low viscosity (25 ° C, 200-250 mPa·s), and is easy to mix with epoxy resin to improve the processability.
2. Pay attention to the environmental protection of curing agent
The curing agent selected should be harmless to the human body and has no pollution to the environment. Ethylenediamine should not be used alone as a curing agent, and a modified amine curing agent should be used as much as possible.
