Micaceous Iron Oxide

Micaceous iron oxide (iron oxide, Fe2O3) is a naturally occurring iron oxide with lamellar shape similar to mica (hence the name). Micaceous iron oxide is characterised by:

 

  • Black colour
  • Lamellar structure
  • High inertness in various media (the iron in the mineral has already been oxidised).

Application

MIO will provide:

 

  • Abrasion resistance: due to its hardness of 6 on Mohs scale, MIO will increase the coating’s resistance to wear.
  • Chemical resistance: due to its lamellar structure and inert nature, MIO will provide barrier properties to the primer and topcoat, and good chemical resistance compared to conventional fillers.

  • Mechanical reinforcement: due to its lamellar structure, MIO will mechanically reinforce the binder matrix.
  • UV resistance: being insensitive to UV radiation, MIO will reduce the coating’s degradation.
