Micaceous Iron Oxide Red main content is a- Fe2O3, the crystal is sheet or plate like hexagonal, it is a large radius to thickness ratio, with diameter from tens of microns to a hundred microns, thickness from a few microns to tens of microns. Mohs hardness of micaceous iron oxide gray is 5.5-6.5, it has good light resistance, heat resistance, weather resistance, and excellent rust resistance, micaceous iron oxide gray does not change colors even at 1000°C.
Other name:( Hematite / Micaceous Ferric Oxide red)
Unique shielding, exceptional heat resistance, superior corrosion resistance, wide application
Chemically inert sheet-iron pigment in the film within the laminate, moisture penetration difficulties, such as alkyd paints with water, chlorinated rubber and epoxy resin used in conjunction, can greatly improve the ability of anti-rust. It should be used in hot and humid areas, factories, mines and marine areas.
Micaceous iron oxide can reflect, absorb ultraviolet light, protecting the paint from damage, have special effect against chalking.
Photo sensitivity weak encountered sunlight, rain, dew, frost, snow, difficult to be damaged, ultraviolet radiation resistant function can be used for anti-corrosion finish.
Does not have chemically react with the paint, the film can maintain long-term flexibility. Also, the flake pigment is not easy to remove during pulverization than the particulate pigment , still play barrier, thus extending the life of the film.
Micaceous iron oxide paint can air spray, high pressure airless spray, roller or brush. Usually long oil alkyd, a dry film thickness of 20-40??m, iron and alkyd paint a cloud of dry film thickness of 40-60 ??m. Layered structure having a high hiding power but other oxide coatings does not have.
Low shrinkage during cure the coating, so that the mechanical strength is increased.
Topcoat laminated sheet-iron have appropriate roughness can remain stable adhesion, after use outdoor two, three months, the film surface partially exposed micaceous iron crystals, which can help increase the adhesion on.
Micaceous iron oxide pigments in the paint film can be formed on the uneven surface to improve adhesion of the second coating.
Micaceous iron oxide red itself withstand 900 ??C high temperature, and with the silicone paint, can be made into high temperature paint.
MIO itself substantially free of lead, chromium and other heavy metals, and can replace red lead and other anti-rust paint.
Flame cutting or welding can be performed, not as red lead and other toxic lead paint hazards easy welders, serious occupational lead poisoning.
MIO is the lowest-quality, cost-effective anti-rust paint, it has been widely used in heavy-duty areas.
For intermediate coat over zinc-rich primer coating, both for the entire film play a good shielding effect closed, effectively improve the permeability of the coating and corrosion protection, increased thickness of the coating, reduced smear cost layer.

When incorporated into a coating film, the lamellar flakes align and interlock to create a tortuous path that limits moisture and corrosive species from reaching the substrate. This is the primary reason MIO is widely used in corrosion-resistant coating systems.
Micaceous Iron Oxide is primarily an iron oxide (Fe₂O₃) pigment processed to a flaky/lamellar morphology that gives it a metallic appearance and barrier properties.
Because of its flake shape, MIO forms interlocking layers in the coating film that create a tortuous path for moisture and corrosive agents — improving corrosion resistance compared with spherical or granular pigments.
MIO is commonly used in alkyd, epoxy, and high-build protective coatings and can be used as an intermediate or topcoat depending on formulation. It is widely used for marine, petrochemical, and industrial steel protection.
