Mica is a naturally occurring inert mineral with a very high aspect ratio; the mineral platelets remain platy particles even after processing has reduced the raw material to an ultra-fine powder. High aspect ratio MicaFort products provide very effective barrier formation in coatings to increase the performance of these in marine coatings even under the most severe conditions such as in marine applications.
The Mica particles orientate themselves within the coating parallel to the substrate ensuring the coating longevity and resistance to chemicals, salt water or other aggressive substances. MicaFort produced from Muscovite Mica is naturally colourless enabling the white, pale and primary shades of coatings to be manufactured without the addition of expensive pigments.
MicaFort improves corrosion resistance
The permeability of the coating film is greatly reduced with the addition of MicaFort as the particles form an impenetrable barrier when applied to the steel structure. The Mica particles align in a parallel overlapping formation. This barrier will prevent water vapour transmission and stop aggressive chemical ingress to the resin system which will significantly reduce the corrosion process on the underlying substrate.
