Organic coatings with anticorrosive pigments are extensively studied for the protection of metals from corrosion attack.The strict environmental regulations for coating applications have brought to the development of both solvent free coatings and non-toxic pigments.This paper presents the results regarding the effect of nano-aluminum powder pigment content on the protective properties of waterborne epoxy films on steel in 3.5 % NaCl solution.The anticorrosive performance of the coatings with 0.5 wt.%,1 wt.%,3 wt.% pigments and none pigment were investigated using electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM).
