A fast curing epoxy resin system for wet molding process was studied.It studied the curing characteristics of epoxy resin when the modified amines worked as master curing agent.The best ratio parameters and castable properties were determined by differential scanning calorimeter(DSC),gelation time tester and mechanical testing machine.The results shown that the gelation time was 48 seconds when the system added 20% curing agent at 120℃,and the curing procession could be completed in 5mins.The curing degree of this system was 98% in this condition,and the resin tensile strength reached 63MPa.Compared with the conventional resin system and domestic products,this system has a significant improved.
