Chromating
Chromating is a type of conversion coating used to passivate steel, aluminum, zinc, cadmium, copper, silver, magnesium, and tin alloys.[1] It is primarily used as a corrosion inhibitor, primer, decorative finish, or to retain electrical conductivity

Black Hexavalent chromating
Isochrome 10 Powder
Properties:- Isochrome 10 Powder blue chromating produces deep blue uniform chromate coating on surfaces deposited of zinc. It is suitable for zinc deposits from cyanide.can be reinforced without any problems. Depending on the immersion time, make-up quantity and working temperature, the chromating produces a medium up to very strong chromate coatings with an optimum corrosion resistance. Isochrome 10 Powder can be applied both in rack- and barrel operation
For blue chromating
Isochrome 25 powder
Properties:Isochrome 25 Powder yellow chromating produces deep yellow uniform chromate coating on surfaces deposited from cyanidic, alkaline and acid electrolytes, can be reinforced without any problems. Depending on the immersion time, make-up quantity and working temperature, the chromating produces a medium up to very strong chromate coatings with an optimum corrosion resistance. Isochrome 25 Powder can be applied both in rack- and barrel operation.
