Curing agent compound use
2017-2-17 16:57:37
Curing agent compound use, can get the result of bring out the best in each other, such as low molecular polyamide curing agent with a small amount of m-phenylene diamine curing agent, as well as room temperature curing, and can make the curing toughness increase appropriately increase the heat resistance at the same time.
Curing agent compound use of trimellitic anhydride (TMA) and methyl benzene anhydride compound using four hydrogen, eutectic mixture low viscosity (25 ℃ and 200 ~ 250 mpa, s), mixed with epoxy resin, improve the manufacturability.
Curing agent composite using the selected curing agent to deal with the human body without harm, on the environment pollution-free, ethylenediamine never used as a curing agent alone, as far as possible using modified amine curing agent.
