BLUSTEIN, Guillermo; DI SARLI, Alejandro R; ROMAGNOLI, Roberto  and  DEL AMO, Beatriz. Study of Anticorrosive Properties of the Iron (III) Benzoate in Solvent Based Paints. Inf. tecnol. [online]. 2006, vol.17, n.3, pp.95-98. ISSN 0718-0764.

This study investigated the inhibitory action of iron benzoate on SAE 1010 steel electrodes in aqueous suspensions using electrochemical assays. The anticorrosive efficiency of this product added to organic solvent-based coatings was also evaluated by means of accelerated weathering tests (salt spray cabinet and humidity chamber). The evolution of the protective behavior of the coating applied on steel panels and immersed in 0.5M NaClO4 solution was periodically checked by electrochemical impedance spectroscopy. The results obtained showed that paints formulated with ferric benzoate provide anticorrosive protection similar to those formulated with zinc phosphate.

Keywords : anticorrosive paints; solvent based paints; electrochemical impedance; corrosion inhibitor.
