3. Solution Maintenance:

1) Analyze the concentration of copper sulfate and free sulfuric acid everyday, control it in the required range, and replenish in time.

2) The consumption of LW-22 is 5kg for each tone aluminum profile treatment, and the addition is according to the production capacity.

3) It’s better to apply electrophoretic coating for sealing after coloring process. It can be advantageous for weatherability and lightfastness as well as achieving a brilliant color on the products.

4) It will be a little fading after electrophoresis process for coloring a light red color (The semi-sealing is required before electrophoresis). It is recommended to prepare two pieces of coloring samples for color-correction before and after the electrophoresis process. So the professional and skilled color-correction operator is required.

4. Packaging and Storage:
