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.
- Coefficient of friction from 0.06 to 0.18 (ISO 16047) thanks to NOF METAL COATINGS EUROPE finishes
- Upholstery can be used with or without a finish
- No hydrogen embrittlement
- Excellent performance for assembly and multiple clamping (with lubricated finish)
- Good resistance to mechanical aggression (test method D24 1312, USCAR 32) and chemical aggression (test VDA 621-412)
- Retains the properties of the coating for exposures up to 300°C
- Paintable
- Electrical conductivity suitable for most applications
- Bimetal compatibility with aluminum
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.
