| Abstract | ||
| Abstract In this work, comparative isothermal and differential thermal analysis of epoxy-polyurea / metal blends were investigated. IGA measurements show fast loss in weight in the first 20 minutes before they reached a constant weight, while the period where about 25 minutes for epoxy alone. This behaviour was explained by the strong network formed by the polyurea complex with epoxy which diminshes its decomposition. Meanwhile, DTA thermograms of most belnds show two distinct exotherms (T2 and T4) while these exotherms are small and not clear in case of epoxy alone. This behaviour may explained by the presence of the metal ions through the blends which promotes the oxidation process. | ||
