Geomet

Geomet®

The GEOMET® product range is a standard worldwide reference for industries requiring high performance thin layer anticorrosion systems. GEOMET® products are completely chrome-free and capable of protecting a wide variety of metallic surfaces. The coatings are well suited for protecting both large and small parts, having either simple or complex geometry. In particular GEOMET® coatings are a worldwide standard for use on fasteners.

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

Characteristics and performances

  • The coefficient of friction can be adjusted to targeted values ranging from 0.06 to 0.20 (ISO 16047) with NOF METAL COATINGS GROUP's selected topcoats
    • Salt Spray Test (ISO 9227)
    • 1000 hrs without red rust
  • No hydrogen embrittlement
  • Excellent assembly and multi-tightening behavior (with lubricated topcoat)
  • Performance maintained at elevated temperatures (up to 300°C)
  • Paintable coating
  • Electrical conductivity for most application processes
  • Bimetallic compatibility with aluminum

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.

  • Thin dry-film, non-electrolytic
    • Salt Spray Test (ISO 9227)
    • 240 hours without white rust
    • 720 hours without red rust
  • Water-based chemistry
  • Passivated zinc and aluminium flakes in a binder, patented chemistry
  • Chrome free alternative to DACROMET® 320
  • Metallic silver appearance

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 – 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® 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
