摘要

Epoxy resins are valued for their excellent toughness and adhesive strength, which are contributingfactors in determining a coating lifespan in aggressive environments. With new challenges in the oiland gas industry, polymers derived from petrochemical-based definitely have become major concern tothe affected industry. Using epoxididized palm olein (EPO) is one of the alternative in the epoxy resinsas minor substitution. This project aims to study the effects of mixing EPO into the conventional epoxyin terms of corrosion resistance. Coating performance was evaluated by comparing conventional epoxyand EPO using low-carbon steel as sample. Electrochemical impedance spectroscopy (EIS) andimmersion test was conducted using 3.5% NaCl to study the effect of corrosion and weight loss on thelow-carbon steel. The results indicated that a small amount (20%) of the EPO is still acceptable interms of cost optimization but reduced the coating performance. However, too much of EPO (40%)had led to accumulation which hinder the coating performance and increased dry film thickness.Furthermore, the resistance against corrosion was affected with additional amount of EPO at 16%reduce (20% EPO) and 95% reduce (40% EPO) with respect to the conventional epoxy. In terms ofcost optimization, the overall cost could be reduced by 13%.
