Abstract

The durability of epoxy resin coating was studied under environments with relative humidity (RH) of 98%-100%, at 55 °C for 900 h, at 65 °C for 700 h and at 75 °C for 400 h, respectively. Peel strength test, dynamical mechanical thermal analysis (DMTA), infrared spectroscopy (IR) and energy dispersive X-ray spectroscopy (EDX) were employed for measurements. Peel strength indicated the development of adhesive property of the coating, DMTA indicated the development of physical property, IR revealed the development of chemical structure, and EDX showed surface element change of the coating. All these results show a good timetemperature equivalence characteristic between humidity aging time and temperature.
