Aluminum Conversion Coating

Aluminum Conversion Coatings are non-decorative coatings applied to aluminum parts to achieve a thin, electrically conductive coating that will provide corrosion resistance. These coatings are also a great base coating for aluminum parts that require painting, as it will aid in the adhesion of the paint to the aluminum.

ⅠPerformance and application domain  
IC-2012 is a kind of liquid product for passivation treatment , applied to chemical conversion coating process for aluminum and its alloys, and not containing Cr+6. After mixing with water, in the dipping and spraying application, it can form an amorphous inorganic coating on metal surface. The coating has the functions as follows:
* It has good adhesion to painting coating and good resistance to corrosion.
* Bare coating has very strong corrosion resistance.
* Coating has lower conductive resistance .
IC-2012 can be used in dipping or spraying process.
IC-2012 coating is with color, which depends on alloy composition and operation conditions
