摘要: The objective of this research was to study the efficiency calcium tripolyphosphate and zinc as anticorrosive pigments for paints in aggressive environments. Alkyd epoxy paints, solvent-borne type, containing 30% by volume (v/v) pigment, were formulated. pigment concentration/critical concentration (PVC/CPVC) ratio fixed at 0.8. In a second stage, water-borne v/v both tripolyphosphates different PVC values (20 25%) also Finally, standardized accelerated (salt spray humidity chamber exposure) electrochemical impedance spectroscopy (EIS) tests used assess protective performance coatings. Analysis interpretation experimental data show that both, tripolyphosphates, inhibit corrosion painted steel panels exposed
