Abstract
Abstract This work intends to investigate the role of NaX zeolite nanoparticles as reservoir of Zn2+ and 2-mercaptobenzimidazole in prolonging the lifetime of an epoxy ester coating. Based on the XPS and SEM/EDX surface analysis and electrochemical data in solution phase, the synergistic inhibition effect of the organic and inorganic species released from the zeolite particles resulted in deposition of a dense protective layer mainly composed of zinc hydroxide, organic inhibitor and organic/inorganic complex on the surface. Accordingly, a synergistic corrosion protection was detected when the NaX zeolite particles doped with Zn2+/mercaptobenzimidazole were incorporated in the epoxy ester coating.
