Abstract: The rheological behavior and exothermal behavior of an epoxy resin system with two available curing agents RIMH 037 and RIMH 038 were studied. The isothermal viscosity and actual exothermal behavior were analyzed for this resin system with six different curing agent mixture ratios. A viscosity model was established after the simulation of the obtained rheological data. The results show that under the same mixture ratio, the pot life was first increased and then decreased as the temperature increased, with 35℃ for the longest. Under the same temperature, the pot life was not obviously changed as the content of RIMH 038 increased. The change law of the pot life indicated by the actual heating test was consistent with the rheological analysis results.

Key words: epoxy resin, rheological behavior, exothermal behavior, pot life
