Zinc Aluminium Flake Coating – Dacromet / Geomet Process

Zinc Aluminium Flake Coating –

Grauer & Weil (India) Limited have a technological tie up with M/s NOF Metal Coating’s Asia Pacific Co. Ltd. of Japan and introduced ‘Dacromet®/Geomet®’ processes in India, in 1996 just as the auto industry boomed in India.

Since then Grauer & Weil have appointed over 20+ sub licensees for providing GEOMET® coatings to all OEM customers  across India.

Dacromet® / Geomet® Process:

Dacrotizing provides outstanding protection to metallic surfaces, against corrosion The coating is known by the name ‘Dacromet®’ and ‘Geomet®’ and contains inorganic silver-grey deposits largely comprising Zinc & Aluminum flakes, uniformly distributed on the entire substrate.

Dacromet® / Geomet® processes are used for protection of various items like fasteners, springs, brake discs etc. The process involves two coats/two bake method to get the desired results. Coefficient of friction for fasteners can be modified using additional layer of top coat. The application of top coat additionally improves protection against corrosion. Both processes provide outstanding protection to metallic surfaces against corrosion at film thickness as low as 6~8 microns.

Growel supplies both, the chemicals and equipment required for Dacromet / Geomet process.

Industry Application

GEOMET® & DACROMET® processes are established, technologically superior and environment friendly and are being used in many industries throughout the world, such as Automobiles, Windmills, Engineering, Electricals & Electronics, White Goods, Mining, Railways, Process Industry and Defence.
