Aging Effect in Different Aqueous Media on Thermal Stability of Epoxy Resin

ABSTRACT
The present work deals with the influence of aging conditions on thermal stability of authentic epoxy resin exposed to different aqueous media. Thermogravimetric analysis (TGA) shows that epoxy samples cured at moderate temperatures are more stable in acidic media than the samples cured at higher temperatures. The complete decomposition temperature of the epoxy resin exceeds 4000C for samples cured at 250C then decreased gradually for samples cured at 32 and 480C respectively.
