micaceous iron oxide - (MIO)

MIO - Micaceous Iron Oxide - is considered an anti-corrosive additive used in many kinds of paints and coating for over 100 years and is perhaps the most important barrier pigment used in coatings to protect structural steel. Its use is much more common in Europe than in the USA. It is regularly used to protect steel surfaces from the elements and corrosion and used on steel boat hulls, bridges etc. The classic example is the Eiffel Tower in Paris. Big Ben in London and the Sidney Harbor Bridge in Australia are other examples. In the USA, MIO based coatings can be found on the Golden Gate Bridge and the San Francisco Bay Bridge. It is also used for durability and reliability on electrical and industrial equipment.

The flake-like gray or red MIO particles align parallel to the coated surface producing a layer of shield of overlapping plates (author's note: I believe this is also the mechanism for the amazing properties of our aluminum pigmented, moisture cured urethane - called Aluthane).

The result is a:

tough barrier surface

excellent UV absorption layer

structural reinforcement of the coating

improvement in intercoat adhesion

improvement of chemical resistance (note: seawater is a chemical environment)
