EPSP407 Water-borne Epoxy Anticorrosive Primer is a water-borne coating used as a primer. Widely used for anticorrosive protection of steel structure surfaces in construction machinery, port machinery, chemical, pipeline, metallurgy and power industries. Water is the dispersion medium; non-flammable and non-explosive, can be diluted and cleaned with water, pollution-free application, safe and convenient transport and storage. Parameters on this page: dry film thickness 40–60 µm; theoretical spreading rate 6.80 m²/kg; number of components: two.

A two-component water-borne epoxy anticorrosive primer; component B is a modified amine hardener; uses active anti-rust pigments such as zinc phosphate, zinc oxide or aluminium tripolyphosphate; the film has high water resistance, saltwater resistance and abrasion resistance, with high adhesion to galvanized, steel and aluminium surfaces. Water is the dispersion medium; non-flammable and non-explosive, can be diluted and cleaned with water, pollution-free application, safe and convenient transport and storage.
Widely used for corrosion protection of steel structures in construction machinery, port machinery, chemical, pipeline, metallurgy and power industries.

All surfaces to be coated must be kept clean, dry and free of contamination. Before application, assess and prepare surfaces in accordance with ISO 8504:2000; remove oil and grease by solvent cleaning per SSPC-SP1; blast clean steel surfaces to Sa 2.5 or clean with power tools to St 3.
Subsequent coat: acrylic, epoxy, modified epoxy and polyurethane coatings.
