Introduction to Epoxy Zinc Rich Primer
Epoxy zinc - rich primer is a high - performance anti - corrosion coating widely used in various industries. It consists of epoxy resin as the base material and a large amount of zinc powder as the active anti - corrosion pigment. The zinc powder in the primer can provide cathodic protection to the steel substrate. When the coating is damaged and the steel substrate is exposed, the zinc powder will preferentially corrode, sacrificing itself to protect the steel from rusting. This primer has excellent adhesion, high hardness, and good chemical resistance, making it suitable for protecting steel structures in harsh environments such as marine, industrial, and infrastructure construction.
