The Present research focuses on the development of a solvent-free epoxy coating with silane-coated zinc oxide for applications in high-temperature environments, specifically targeting Gas Oil Separation Plant (GOSP) tanks, submerged areas, DGA columns, desulfurization units, and sour gas treatment facilities. This specialized coating is engineered to withstand hydrocarbon solutions at temperatures up to 150°C. By incorporating silane-coated zinc oxide into the epoxy matrix, the resulting coating exhibits enhanced adhesion, corrosion resistance, and mechanical properties. Formulation optimization ensures excellent film performance, low viscosity, and easy application using conventional airless spray equipment. Performance evaluations encompass autoclave (chemical resistance), immersion, cathodic disbondment and electrochemical impedance spectroscopy (EIS) tests. Results demonstrate superior adhesion, exceptional chemical resistance, and improved mechanical strength of the silane-coated zinc oxide-based coating, affirming its durability and long-term protective capabilities in the harsh environments encountered in GOSP facilities. The developed coating not only offers a cost-effective solution for reducing maintenance costs but also effectively shields against corrosion and chemical degradation. Overall, this study presents a promising approach for the development of high-performance coatings suitable for the challenging conditions encountered in GOSP tanks and associated equipment.
