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.

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
