The effect of pigment volume concentration (PVC) on the antistatic and anticorrosive properties of waterborne antistaticanticorrosive epoxy coatings was studiedThe element components of conductive pigments were analyzed by X-ray energy dispersive spectrometer (EDX)

and the protective properties and morphology of coatings with different PVCs were characterized by electrochemical impedance spectroscopy (EIS) and scanning electron microscope (SEM) respectivelyThe optimal PVC of this waterborne antistatic anticorrosive epoxy coating was determined as 35% based on the results of the tests of mechanical

physical and corrosionresisting performance

and the analysis of EISThe results showed that the corrosionresisting performance of coatings improved at first with increasing PVC and then decreased after PVC exceeded 35% in the range of PVC from 25% to 45%.
