EPP306 Epoxy Anticorrosive Primer is an epoxy coating used as a primer. A multipurpose primer for new construction or maintenance, easy to apply, high-performance epoxy anticorrosive primer, replacing zinc-rich primer for acid/alkali splash or intermittently immersed areas, suitable for overcoating with various high-performance topcoats. A two-pack, fast-drying epoxy primer suitable for production-line application, with good abrasion resistance and low mechanical damage, lead- and chromium-free, in iron red or brown. Parameters on this page: dry film thickness 75 µm, theoretical spreading rate 5.73 m²/kg, number of components two.

Per SSPC-SP1, remove oil and grease with solvent; where necessary, remove weld spatter and grind welds and sharp edges; the surface to be coated must be clean and dry. Blast cleaning: blast to the American standard SSPC-SP10 (Sa 2.5 ISO 8501:2007), then apply the epoxy anticorrosive; if the surface has oxidised, re-blast to the specified standard. Primed surfaces: welds or damaged areas shall be blasted to the American standard SSPC-SP10 (Sa 2.5 ISO 8501:2007); if the surface shows severe scattered damage, full sweep blasting is required.
The product cures slowly below 5 °C; for good results, the substrate temperature shall be above 5 °C.
