Chromium-free passivation solution for aluminum materials Anti-oxidation and color-preserving passivation treatment for aluminum materials

1. Product number: Q/YS.201 (Yishun brand)

2. Product features:

This product is suitable for forming a chromium-free chemical conversion film on the surface of aluminum and aluminum alloys. The obtained chromium-free chemical conversion film has excellent corrosion resistance and can be used as a pre-treatment for paint and coating. This product does not contain harmful substances such as chromium ions and heavy metals. Passivated aluminum is highly resistant to corrosion. And it looks great. The white passivation film is thick and firm, which can maintain the long-term luster of the aluminum surface. This product is environmentally friendly.

3. Product indicators:

1 Properties: Colorless transparent liquid.

2 Ratio: 1.1±0.02.

3PH value: acidic

4 temperature: room temperature.

5 concentration: stock solution

6 Processing time: 3-5 minutes.

4. How to use:

Immerse the clean aluminum parts in the passivation solution for 3-5 minutes, wash and dry. Do not overlap the pieces until they are dry, when the pieces are completely dry they can be put together.
