Our history starts with our passion.

Inventor of zinc flake coatings.

Our R&D department began using zinc dust in ZINCROMETAL® coatings in the 1970s. This first invention made it possible to effectively prevent corrosion and reduce the weight of vehicles by using thinner formable and weldable body steel sheets. Traditionally, phosphate and oil as well as zinc and cadmium electroplating were used to protect fasteners and various metal parts.

The idea of using zinc flakes in a water-based dispersion led to a revolutionary invention: DACROMET®. The thickness of the coating was reduced thanks to the specific shape of the flakes. The very good corrosion resistance was also enhanced by dry lubrication with PLUS® topcoats. In addition, the coating application process eliminated the risk of hydrogen embrittlement of high-grade steel parts while saving water since it does not require a rinsing step.

Anticipating regulations and market changes, NOF Metal Coatings Group has improved DACROMET® to create GEOMET® and continues to innovate with modern coating solutions that combine high performance with an ever smaller environmental footprint.
