Epoxy Zinc Rich Primer is a high-performance anti-corrosive coating containing a high percentage of zinc dust, providing cathodic protection to steel surfaces. This primer offers excellent resistance against corrosion in aggressive industrial and marine environments. Epoxy zinc rich primers are widely used for structural steel, bridges, power plants, oil & gas installations, refineries, and heavy engineering structures. This primer is strictly designed for metal surfaces and is not suitable for floor applications.
