Electrochemical impedance spectroscopy (EIS), which has been previously demonstrated to be a suitable method to determine the CPVC coatings [R.E. Lobnig, W. Villalba, K. Goll, J. Vogelsang, I. Winkels, R. Schmidt, P. Zanger, J. Soetemann, Development of a new experimental method to determine critical pigment-volume-concentrations using impedance spectroscopy, Prog. Org. Coat. 55 (2006) 363–374.], was applied to four series of coatings with components typical for solvent based commercial organic anticorrosion coatings, and to three series of coatings with nanopigments. For all coatings, the CPVC determined using EIS correlated very well with the CPVC determined from cross-sections with electron microscopy (SEM). The EIS method was also useful for the coatings with nanopigments, for which pores were too small to be detected by SEM-analysis of cross-sections.
