Polyurethane/micaceous iron oxide coatings Available to Purchase

Micaceous iron oxide coatings are becoming more and more popular in Europe in steel construction, both as an undercoat and as a topcoat. This is mainly due to the protecting platelet structure of the micaceous iron oxide, which protects the resin component from oxidative uv degradation on exposure to the weather. It is also fairly common to combine them with aluminium pigments. This reinforces the scale‐like character of such coating systems and gives a light, metallic appearance. Because of the natural dark colour of micaceous iron oxide, the choice of shades is rather limited. There are nevertheless no problems in matching certain dirty shades as are found, for example, in standardised colour cards.
