Abstract

The anticorrosive properties of different epoxy primers containing polyaniline, poly (ortho-ethoxyaniline) or zinc phosphate were evaluated on mild steel in saline environment (3.5% wt NaCl).

The obtained results from electrochemical measurements and immersion tests show that primers containing substituted polyaniline provide better corrosion protection compared to conventional zinc primers and polyaniline primers which are supplied by Zipperling Kessler & Co.

The effectiveness of our primers is explained by the good solubility of substituted polyaniline in the selected solvents.
