The epoxy MIO intermediate paint is composed of epoxy resin, mica iron oxide-based anti-rust pigments, solvents, additives and curing agents. The epoxy mica intermediate paint has good mechanical properties, the paint film is tough, impact-resistant. It has good resistance to penetration and good shielding performance. The epoxy mica intermediate paint has excellent corrosion resistance, oil resistance and water resistance. It has relatively low requirements for the treatment and rust removal of the substrate, and excellent adhesion with the subsequent paint film and has a wide range of compatibility.
Longer coating interval

In steel structure and bridge heavy-duty anti-corrosion system, the intermediate paint usually chooses epoxy mica intermediate paint, although it can also be used as an anti-rust primer. As an important anti-rust pigment, mica iron oxide is widely used in alkyd, phenolic and chlorinated rubber coatings, but in modern heavy-duty coatings, the most important is the epoxy mica intermediate paint. Because mica iron oxide has a reflective effect on ultraviolet rays, and the mica will form a certain rough surface on the coating surface, it has long-term recoatability, unlike other epoxy coatings that have strict restrictions on the recoat interval. In this way, epoxy MIO paint will improve the long-term recoatability of the entire coating solution, making it suitable for painting in the workshop and then transporting the steel structure to the site for splicing, repairing and recoating the topcoat. At present, in many bridge projects, epoxy MIO paint is used as the intermediate paint on the epoxy zinc-rich primer.
