The curing properties and chemorheological behaviors of the three heat resistant glyceramine epoxy resin systems for the injection repairing were measured by the isothermal differential scanning calorimetry and the rotational rheometer to investigate the curing cycle and the chemorheological characteristics of the resin systems. The MF-4101/ZH110/DMP-30 resin systems were proved to be the most suitable formulation for injection repairing by comparing the curing conditions and viscosities of the three resin systems. The Daul Arrhenius model and the highorder exponential fitting model were established to analyze the isothermal viscositytime curves of the resin system. Results show that the accuracy and the applicability of the high-order exponential fitting model for viscosity predicting are superior to the Daul Arrhenius model. The predicted results of the high-order exponential fitting model are in good agreement with the experimental data. This phenomenological formula based on the above model can be used to predict the processing windows of injection repairing resin systems. 
