Geomet® (Zinc flake)

Geomet® is a non-electrolytically applied zinc flake coating with a silver finish.

Geomet® is used for corrosion protection on steel and cast-iron items. Geomet® is the only water-based zinc flake coating method. The unique process enables optimal friction control and corrosion protection.

Provexa Surface Technology AB is the only licence-holder in Scandinavia for the Geomet® chromium-free coating technology of N.O.F Metal Coatings Europe s.a.. This technology offers an environmentally friendly alternative to the coating or galvanizing of smaller metal products – using solvents, mechanically or via electro-plating – particularly for the automotive industry.

A zinc-aluminium laminated coating is applied in a fully automated production line. This ensures extremely high corrosion resistance at a low layer thickness. A second important advantage is that hydrogen brittleness cannot occur. We can describe a product as a Geomet® product once correct layers have been applied because only then is the required protection offered. Another layer, the top coat, allows the product’s friction coefficient to be efficiently regulated. This is extremely important for various applications.

The Geomet® procedure is chromium-free and as such meets the most recent EU guidelines.

Geomet® is PFAS-free.
