Epoxy Intermediate Coat is a high-build protective coating applied between primer and topcoat to enhance overall coating system performance. It improves film thickness, provides additional corrosion resistance, and ensures better adhesion of the final finish coat. Epoxy intermediate coats are widely used in industrial coating systems for steel structures, pipelines, storage tanks, power plants, refineries, and heavy engineering applications. This coating is strictly used on metal surfaces and is not suitable for floor applications.
