Epoxy anticorrosive paint is a type of coating primarily composed of epoxy resin and modified epoxy resin as the main film-forming substances. It offers excellent adhesion and chemical corrosion resistance, good alkali resistance, and a hard coating, making it one of the most important varieties of anticorrosive paints. It is mainly used for corrosion-resistant coatings, such as the internal and external walls of large chemical equipment and pipelines, and can also be applied to non-metallic surfaces and electrical appliances, pipeline instruments used in humid tropical conditions. Varnish can be used as a primer or topcoat for metal surfaces.
