EPP304 Epoxy Aluminum Tripolyphosphate Primer belongs to epoxy coatings and is used as a primer. A high-performance primer with excellent anti-corrosive performance and free of harmful heavy metals such as lead and chromium; it provides excellent adhesion to steel and non-ferrous metal surfaces, and the film is tough and abrasion resistant with good oil resistance, water resistance and chemical resistance. Widely used for corrosion protection of steel structures in port machinery, construction machinery, petrochemical and pipeline fields. Brown red, white, grey and other colours; a two-component epoxy anti-corrosive primer prepared from epoxy resin, aluminum tripolyphosphate and amine curing agent. Parameters on this page: DFT 60–110 µm, theoretical spreading rate 8.03 m²/kg, number of components two-component.
