In the oil, gas and petrochemical industries the greatest costs are those associated with material failures due directly to corrosive-erosive degradation of surfaces and components of the pipelines. These results in the frequent repair and replacement of parts which accrues costs associated with loss in revenues in downtime and maintenance [1]. In the current study, a dip-coating method was exploited to provide a coating layer of epoxy resin on 316L and 304 stainless steel plate. Epoxy resin was converted to cationic tertiary type amine resin. This cationic epoxy resin, which contains ammonium group in the end of the polymer chain, was synthesized by ring-opening reaction of an epoxy resin with secondary amine in the presence of a proton donor. A layer of resin was successfully deposited on the stainless steel plates and physical properties of the layer were assessed. A detailed study aiming to obtain reliable information of coating properties was carried out. The electrochemical corrosion results showed that epoxy layer has a positive behavior on protections of stainless steels alloys at the early degradation time point. Scanning electron microscopy observation was also used to study the surface morphology before and after coating. Tafel extrapolation method and Tafel slope constants were used to calculate the polarization resistance.
