Wuhan University of Technology develops a new modified epoxy resin

Wuhan University of Technology in February 2004 modified the development of epoxy resin, respectively, the new epoxy resin has a low viscosity, high strength, suitable for composite industry RTM, centrifugal casting, pultrusion and other idle molding process.
The modified epoxy resin casting body has excellent mechanical and physical properties. According to the introduction of China Epoxy Resin Industry Association, it has the following characteristics:
The initial viscosity (room temperature) mPaS 60 ~ 100;
Curing temperature 11 °C 2h, 150 °C 4h;
Tensile strength (MPa) 87-11;
Tensile modulus (GPa) 4.5;
The bending strength (MPa) 131 ~ 180;
Flexural modulus (GPa) 2.8 to 4.0;
Compressive strength (MP)133
