A two-component water-borne micaceous iron oxide epoxy intermediate coat pigmented with lamellar micaceous iron oxide, providing high permeability resistance and effectively isolating corrosion by water molecules, chemical media and oxygen. On film formation the flakes align in parallel, forming an overlapping scale-like structure; good anticorrosive and heat resistance, and good intercoat adhesion with most water-borne topcoats.
