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.
Key words: Epoxy primers containing substituted polyaniline, polyaniline primers.
