Corrosion protection by the organic metal polyaniline: results of immersion, Volta potential and impedance studies.
Properties of the new polyaniline containing primer CORRPASSIV sealed with two different top coats are characterised and compared with top coated samples using no or a conventional zinc-rich primer. Measurements were made using scanning Kelvin-probe (SKP), electrochemical impedance spectroscopy (EIS), voltammetry and analysis of iron and zinc content in electrolytes for testing. Results are presented and the powerful corrosion protection using the organic metal is shown.
