In petroleum industries, metals can be exposed to contaminants that can cause corrosion. Coating will reduce the risk of corrosion to the substrate to which it is applied by resisting the movement of moisture and contaminants to the surface which cause the substrate to corrode. Palm olein has the characteristics as coating compound and the ability to prevent or inhibit corrosion. This study is focusing on three main objectives, which are to develop a coating compound from palm olein for oil and gas industry, to study the effects of palm olein as a coating compound in protection against corrosion and to study the adhesion of the coating compound on the surface of material. Formulated coating compound consists of palm olein, diethylenetriamine, epoxy and turpentine. During the formulation process, the mixing was repeatedly done as to obtain the optimum product. The turpentine was added to dilute the compound to a certain viscosity suitable for application on an aluminium plate. Coating process was done on the aluminium plates by using a dip coater to obtain a uniform thickness of the coating, after it was cured in an oven. After about 3 weeks, the sample was taken out from the oven and was let to down cooled and was stored for the corrosion test. Two types of corrosion test were done, which are the weight loss test and polarization test. The corrosive medium used in this work was 1 M HC1. The optimum composition was formed to be 15 ml palm olein, 4ml diethylene triamine, 11 ml epoxy and 10 ml turpentine. The result also showed that the scratched surface provided the best adhesion of the coating compound on the metal surface. The scratched surface of the samples had larger surface area, allowing improved wetting of the substrate and in turn improved adhesion. The development of coating material should meet up the production requirements and the performance specifications of the coating.
