Chromating for Aluminium Chemical Manufacturers
We have different types of Aluminium Treatment or Chromating chemicals products.
Aluminium Treatment or Chromating chemicals
Chromating or chromate conversion coating are extremely thin chemical coating that provide couple of desirable characteristic to the surface of aluminium, Iron and zinc parts to enhance corrosion resistance.
It is important to provide clean, grease free surface before chromate application.
There are four types of Chromating Chemicals
1. Aluminium Degreaser
This Type of Degreaser remove thin film from aluminum Component.
2. Aluminum etching
The process applies strong chemical etchant solution to remove unwanted part in the work piece material. It is basically corrosion control process.
3. Yellow Chromating
Yellow chromating or Yellow chromate is a type of hexavalent chromium coating that suitable for aluminium to provide high corrosion resistance and paint adherence.
Drying temperature must not pass over 650C for this chromating.
4. Green or Transparent Chromating
Green chromating is type of trivalent coating that provides good paint adherence and corrosion protection to aluminium surface. Green chrmating coating on aluminum surface can range in color from mate to iridescent green.
Drying temperature must not pass over 850C for these chromating.
