Study on the Properties of the Low Viscosity, Low Heat Liberation and High Toughening Curing Agent for Epoxy Resin

Except for the curing property of the curing agent based on the self-made modified amine agent for epoxy resin, the mechanical property of curing productions were studied in this paper. The results showed that the curing agent had many properties of the low heat liberation, low viscosity, high toughness and room temperature curing. It is suitable to be used as the special purpose curing agents for architectural structural adhesive and cracking filling adhesive, moreover it has an extensive applying prospective in wet way process for composite materials and outdoor construction. Moreover, the epoxy systems based on the curing agent show excellent insulated and dielectric properties and could be used as promising pouring materials for dry type transformer and mutual inductor.
