EPP301 Epoxy Iron Oxide Red Shop Primer is an epoxy paint, used as a primer. Used on automatic shop production lines as a pretreatment primer for shot- or sand-blasted steel surfaces, for temporary protection with an anti-rust period of 3–6 months. It is a room-temperature-curing shop primer, fast-drying, with excellent physical and mechanical properties, good compatibility with various primers, and free of metallic zinc, which avoids harm to the human body from zinc fumes during welding. Parameters on this page: dry film thickness 25 µm, equivalent to 100 µm wet film, theoretical spreading rate 8.7 m²/kg, number of components: two.
