EPSP408 Waterborne Epoxy Anticorrosive Topcoat is a waterborne coating used as a topcoat. Widely used for corrosion protection of steel structure surfaces in construction machinery, port machinery, chemical, pipelines, metallurgy and power industries. A two-component waterborne epoxy anticorrosive topcoat; component B is a modified amine curing agent. The film has strong adhesion and good abrasion resistance, with excellent water, chemical and solvent resistance. Parameters on this page: dry film thickness 40–60 µm, theoretical spreading rate 8.36 m²/kg, number of components two.

A two-component waterborne epoxy anticorrosive topcoat; component B is a modified amine curing agent. The film has strong adhesion and good abrasion resistance, with excellent water, chemical and solvent resistance. Water is the dispersion medium; non-flammable and non-explosive, tools can be thinned and cleaned with water, application is pollution-free, and transport and storage are safe and convenient.
Widely used for corrosion protection of steel structures in construction machinery, port machinery, chemical, pipeline, metallurgy and power industries.
