Dip Coating Solution

Aum Dacro Coating offers Dacromet®, a Dip Coating Solution. The Dacrodip solution is a dispersed aqueous solution made from metallic zinc and aluminium flakes, chromic acid and glycol, etc. For coating, the duly cleaned components are dipped into it and any excess solution is removed by spinning. Then the components are heated to about 300°C in an oven in a closely controlled atmosphere. The hexavalent chromium gets reduced to trivalent chromium, i.e., an insoluble amorphous oxide. This acts as a binder for the many overlapping flakes of zinc and aluminium to form a film. At the same time the chromic acid in the solution also reacts with the substrate forming a chemical bond providing a strong adhesion. Aum Dacro Coatings is a dip-spin coating unit for "Dacromet Coating" and "Geomet Coating" of automobile parts, in technical collaboration with Nippon Dacro Shamrock Co Ltd, Japan, through their Indian arm M/s Grauer & Weil (I) Limited. Dacromet and Geomet are technologically advanced and environment friendly solutions being used in many industries throughout the world, such as automobile, engineering, electrical appliances, shipping, railways, mining, process industry, military, etc., since a very long time.
