April 20, 2024
By admin

GEOMET® 321 is applied to protect fasteners and many types 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.

Water based Zinc Aluminum Flake coating system protect against corrosion.

Completely chrome-free and capable of protecting a wide variety of metallic surfaces, these thin dry-film basecoat are well suited to coat various metal part with simple or complex geometry, both large and small.

GEOMET® can be combined with PLUS® top coats to provide a very broad range of friction coefficients.

CHARACTERISTICS OF GEOMET®

Chromium Free Water Based Chemistry
Green/Eco Coating System- No Pollution Generate From The Process
Very Thin Layer With Better Converge
Excellent Anti-Corrosion Performance
Excellent Heat Resistance
Free From Hydrgen Embrittlement
Minimize Galavanic Corrosion
REACH,ROHS,ELV &WEEE Compliant
Approvals from Global OEM’S
World Wide Net Work

TYPES OF GEOMET®

GEOMET 720

GEOMET^® 720 is applied to protect fasteners and many types of metallic parts from corrosion and is used in many industries. It can be combined with PLUS^® topcoats to provide a very broad range of friction coefficients. It is the reference zinc flake coating in Asia.

Thin dry-film, non-electrolytic
Water-based chemistry
Passivated zinc and aluminum flakes in a binder, patented chemistry
Metallic silver appearance

GEOMET 500

GEOMET^® 500 is applied to fasteners and many type of metallic parts to protect from corrosion, and it is used in many industries

Thin dry-film, non-electrolytic, self-lubricated
Water-based chemistry
Chrome free alternative to DACROMET® 500
Metallic silver appareance

GEOMET 360

GEOMET^® 360 has been specially formulated to protect brake discs against corrosion. The brake disc surface can be totally treated with a coating at a thin layer, still providing high performances without any influence on braking characteristics. GEOMET® 360 is obtained from a water-based dispersion of zinc and aluminium flakes. The color of the coating is silver Characteristics and performance*

Cosmetic protection: the brake discs can be seen through the alloy wheels. The aluminium silver color of GEOMET® 360 integrates perfectly with the style of alloy wheels
Braking behavior: the low thickness of the coating on braking surfaces does not damage the quality of braking during the vehicle first use and enables a temporary protection of brake discs surfaces
Temperature resistance (400°C): it enables to keep an excellent corrosion resistance on vehicles
Protection inside the vents: no oxidation inside the fins вЂ� better thermal exchange while braking
For after-market, GEOMET® enables to assemble the brake discs on vehicles without pre-degreasing (dry protection)
The stronger corrosion protection of GEOMET® on the hub mounting surface makes brake disc dismounting easier

GEOMET 321

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.
