EPE312 Epoxy Ester Iron Oxide Primer belongs to epoxy paints and is used as a primer. Light yellow, suitable for aluminium and aluminium-magnesium alloys; used with a phosphating primer, it provides strong intercoat adhesion and can greatly improve the salt-spray resistance of the coating film. Single-pack; iron oxide red or light yellow. Parameters on this page: dry film thickness 40 µm equivalent to 87 µm wet film, theoretical spreading rate 10.3 m²/kg.
