Abstract Acrylic-polyurethane coatings have been successfull y used in many places,such as marine environment and automobile industry for the ir excellent protective property.The anti-corrosion performance of acrylic-polyu rethane coatings with TiO2 at different pigment volume concentration(PVC) has been studied by electrochemical impedance spectroscopy(EIS).Experimental results showed that,PVC of TiO2 had remarkable effect on the anti-corrosion propertie s of acrylic-polyurethane coatings.Within the PVC value that had been studied,40 % PVC coating had the best anti-corrosion performance.

Key words: acrylic-polyurethane coatings anti-corrosion performan ce EIS
