Anodic oxidation surface conditioning agent

1. Introduction:

It is used for the pretreatment of dyeing after anodizing and can effectively prevent poor dyeing caused by acid release in complex parts with many blind holes and threaded holes.

To avoid problems such as whitening and mottling caused by insufficient water washing, reduce the introduction of oxidation solution, and extend the service life of dyes;

The dyeing effect is particularly good for die-cast aluminum with a loose surface.

2. Traits

Acidic white powder

3. Precautions for operation

1.Please note that during storage, this product may form lumps and undergo slight discoloration, which has no adverse effect on the usage effect.

2. Please crush this product into powder before use to ensure complete dissolution.

3. Long-term immersion will cause the deterioration of the oxide film. Stirring can be carried out to improve solubility and bubbles will be produced. The effect is even better when used in combination with ultrasonic waves.

When the tank is opened (50g/L), the PH value is approximately 2.0. The acid and alkali carried out will cause PH changes. At this time, the PH should be adjusted regularly.

5. The solution may gradually turn brown over time, but this does not affect the product performance.

6. The combined use of cathode or alternating current electrolysis (about 3V) yields better results, but high-voltage electrolysis can cause deterioration of the oxide film. It is necessary to conduct tests in advance for confirmation.

4. Packaging:
