EPM321 Epoxy Micaceous Iron Oxide Anticorrosive Paint/Intermediate Coat is an epoxy coating used as a primer. It therefore has high sealing properties, good heat resistance and anticorrosive performance, and is compatible with most coatings. Two-component packaging, grey or reddish brown, primer or intermediate coat. Parameters on this page: dry film thickness 100 µm, theoretical spreading rate 5.33 m²/kg, number of components: two-component.

Two-component packaging, grey or reddish brown, primer or intermediate coat.
It can be used as an anticorrosive primer and also as an additional coat over anticorrosive paint to increase sealing and anticorrosive performance. It is a barrier material containing a high pigment volume concentration of gamma-phase Fe2O3 flake pigment, which after film formation can be oriented, overlapped and arranged in parallel to form a fish-scale-like overlapping structure. It therefore has high sealing properties, good heat resistance and anticorrosive performance, and is compatible with most coatings.
