Product Details

This product is suitable for addition to the electrolytic stannous coloring solution as a stabilizing enhancer.

Anodal ® Color S - 2 is a high-performance concentrated sulfuric acid solution containing the most suitable ratio of stabilizers and color strength enhancers.

It can improve the stability and coloring power of stannous sulfate electrolytic coloring. Anodal ® Color S - 2 In the divalent tin coloring solution, it ensures

good electrolytic stability, regenerability, and consistent color effects.

Anodal ® Color S - 2 It has the following advantages:

- Excellent bath stability

- Outstanding coloring power

- Enhanced dyeing power

- Excellent direct current stability

Anodal ® Color S - 2 It is recognized for its outstanding function of reducing the consumption of divalent tin. The coloring rate and electrolytic coloring power

have both significantly increased.

- pH Point: 0.8 - 1.0

- When preparing a new electrolytic coloring bath, it is recommended to first add half the volume of deionized water or distilled water. For every

of divalent tin requires adding pH ml Anodal 0.9 solution. To achieve consistent coloring effects, it is recommended to conduct regular bath solution testing. A small amount of 0.1 excess use

4 . is harmless (up to twice the required value), and in fact, the coloring remains reliable.

Anodal ® Color S - 2 Bath solution supplementation can rely on experience, but the concentration can also be tested (see section for details). We recommend using a filter to remove insoluble impurities. 100
