Double salt electrolytic coloring for aluminium

The product is composed of antioxidant, reducing agent, complexing agent, dispersant, penetrating agent and potential regulator,etc.

Product Detail
 Feathers


1. This product is white powder, water-soluble, and stable in performance.

2. Electrolytic coloring additive is composed of antioxidant, reducing agent, complexing 

    agent, dispersant, penetrating agent and potential regulator,etc.


  Advantage

1. The antioxidant contained can prevent the stannous ions from autoxidation effectively, 

    therefore reduce the stannous sulfate consumption. 
2. The complexing agent contained can prevent the tetravalent tin from hydrolyzing, so as to 

    maintain the tank solution long-term clean 
3. Its good dispersity ensures good gloss of colored profile.
4. Good stability, all the compositions and the rate are stable normally.
5. Its excellent performance in dispersity, complexing and penetration ensures small color 

    difference under wide technical conditions.
