The world reference for anti-corrosion

GEOMET® 321 is used to protect fasteners and all metal parts from corrosion in many industrial sectors. It adapts to a wide range of clutches with the addition of the corresponding PLUS, ® DACROLUB® or GEOKOTE® finishes. In zinc flake technology, its diffusion is the widest.

Thin, non-electroplated coating

Water-based chemistry

Bonded and passivated zinc and aluminum flakes, patented chemistry

Metallic silver color

Features & Performance

The GEOMET® 321 alone or in combination with the range of finishes from NOF METAL COATINGS EUROPE passes the most stringent cyclic corrosion tests. It protects parts from rust even after mechanical damage, such as stone chipping, thanks to its self-healing property. It also ensures bimetal compatibility with aluminum alloys. Its nominal thickness can be adjusted (from 6 to 15 μm and from 1 to 3 layers depending on the type of application process) to meet the expected performance.
