extract and zinc cations was suggested as a pretreatment prior to application of the epoxy
coating. According to the electrochemical data and results of SEM-EDS and XPS surface
analysis, the behavior was found to arise from deposition of a protective layer consisting of
zinc hydroxide, adsorbed organic molecules (from ML extract) and complexes of the
released organic species with Zn and/or Fe cations at the primer/mild steel interface …
