The study of the relationship between curing conversion and the properties of the material is critical for optimizing the performance of epoxy materials. In this article, the change in the thermo-mechanical and corrosion resistance properties of the diglycidyl ether of a bisphenol A/diaminodiphenylsulfone epoxy system with curing conversion was studied using various instruments. The water sorption process showed the opposite trend of equilibrium water content with curing conversion at high and low temperatures, which was found to be related to different mechanisms by infrared spectroscopic study. The mechanical tests and corrosion resistance (EIS) experiments showed an optimized performance region at a curing conversion close to ca. 85%.
