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
(test VDA 621-412) resistance
Performance maintained at elevated temperatures (up to 300°C)
Paintable coating
Electrical conductivity for most application processes
Bimetallic compatibility with aluminum
High corrosion re sistance *
