A COMPARISON OF NATURAL AND SYNTHETIC MICACEOUS IRON OXIDE

Micaceous iron oxide (MIO)-pigmented undercoats and finishes provide long-term corrosion prevention for structural steel work. For more than a century, bridges, railway gantries, pipework, and harbor facilities have been protected by MIO paint systems. Today, MIO is a valuable ingredient in high performance coatings based on modified alkyds, phenolic resins, acrylics, vinyl copolymers, and others. In recent years, a synthetic form of MIO has been produced and manufacturers have claimed its superiority over the natural product. This article outlines the procedures followed for the comparative microscopic examination of the MIO pigments in question. In addition, a review is made of a cross section of steel substrate to which epoxy resin-based MIO coatings were applied. Details of the findings are provided.
