Abstract
Abstract As commercial paints have a complex composition, this work was carried out on a model epoxy system (DGEBA/DAMP) with or without pigment (TiO2). Firstly, physico-chemical properties of the composites free films were studied by using {DSC} and {DMA} and compared to those of the sole resin. Then, composites films were applied onto steel panels and were immersed in 3 wt.% NaCl solution at different temperatures (30, 40, 50 and 60
