titre-geomet-321

The world’s choice for corrosion protection

GEOMET® 321 is applied to protect fasteners and many type of metallic
parts from corrosion and is used in many industries. It can be combined
with PLUS, DACROLUB® or GEOKOTE® topcoats to provide a very broad
range of friction coefficients. It is the most widely used product in zinc
flake technology.

  • Thin dry-film, non-electrolytic
  • Water-based chemistry
  • Passivated zinc and aluminium flakes in a binder, patented chemistry
  • Chrome free alternative to DACROMET® 320
  • Metallic silver appearance

Characterictics and performance*

  • The coefficient of friction can be adjusted to targeted values ranging from 0.06 to 0.20
    (ISO 16047) with NOF METAL COATING GROUP’s selected topcoats
  • It can be used with or without topcoat
  • No hydrogen embrittlement
  • Excellent assembly and multi-tightening behavior (with lubricated topcoat)
  • Good mechanical damage (test method D24 1312, USCAR 32) and chemical resistance to VDA 621-412 test
  • Performance maintained at elevated temperatures (up to 300°C)
  • Paintable coating
  • Electrical conductivity for most application processes
  • Bimetallic compatibility with aluminum

 

* Results may vary depending on substrate, geometry of parts and type of application processes

Application process

GEOMET® 321 can be applied by Dip-Spin, Spray, Dip-Drain-Spin using bulk or rack
