Anodal® SUAC

Aluminum Chemical

Edition Date :
July 08, 2021
Anodal® SUAC is used on a large scale in anodic integral coloring processes. The function of Anodal® SUAC is to regulate the current potential characteristic and the redissolving power of the oxide layer. The colors produced by this anodic process are outstandingly resistant to light and weathering. 
Colors range from bright bronze to black, depending on the alloy.

Benefits

  • Diluable with water in any proportion
  • Outstanding resistance to light and weathering

Applications

Anodal SUAC is used on a large scale in anodic integral coloring processes. The distinctive feature of these processes is that the color is produced in the oxide film itself as it is formed on the metal. The color is due to elementary inclusion of the components of the alloy (e.g. Si, Mn, Cu or Cr) in the coating and to the use of special electrolytes.

The function of Anodal SUAC is to regulate the current potential characteristic and the redissolving power of oxide layer. The colors produced by this anodic process are outstandingly resistant to light and weathering.
