Increasing concerns over the health and ecological effects of hexavalent-chromium has inspired the development of alternative approaches and technologies for various coating types.

At the center of the innovation efforts are companies like MacDermid, who’s development of chromate conversion coatings for plated coatings helped seed developments in the field of aluminium treatments. Until now, most non-chrome conversion coatings have been based on a combination of organic polymers and fluoride compounds. While these types of products have excellent paint adhesion characteristics, in most cases, they have no corrosion resistance properties. Based on that deficiency, MacDermid have developed a product range that has shown to be both safe and effective as a true replacement for the hexavalent-chrome systems…Iridite NCP.

Iridite NCP provides both high adhesion values for paints and powder coatings as well as excellent corrosion resistance in its own right. This means that even unpainted areas of aluminium are protected against corrosion. Iridite NCP is the safe, reliable and cost effective alternative to chromate based pretreatments for aluminium.
