LW-22 Copper Salt Electrolytic Coloring Additive is a remarkable Anodizing Agent, presented as a light blue clear liquid. In the Aluminium Anodizing Process, it plays a crucial role in coloring aluminum profiles after anodization, especially for high-quality external wall decorative products.
The strong dispersing and complexation ability of LW-22 is one of its key strengths. Its potent complexing ability enables it to form stable complexes with metal ions in the coloring solution, which is essential for maintaining the stability of the entire coloring system during the anodizing and coloring procedures. This stability is vital for achieving consistent results, whether aiming for a Gold Anodized look or other color finishes on the aluminum profiles.
One of the most notable features of LW-22 is its effectiveness in preventing the edge effect that is commonly encountered in copper-salt coloring. This ensures a more uniform color distribution across the surface of the anodized aluminum profiles, enhancing their aesthetic appeal.

LW-22 also exhibits excellent stability, along with good homogenization and reproducibility performance. It has remarkable reproducibility, meaning that regardless of how many times the coloring process is repeated, it can consistently achieve highly similar coloring effects. This provides reliable quality assurance for large-scal
e production in the Aluminium Anodizing Process.
After the anodizing and coloring processes are completed, when it comes to Cleaning Anodized Aluminum, the properties of LW-22 can have a positive impact. Since it helps in achieving a more uniform and stable color layer, it makes the anodized and colored surface less prone to uneven staining or damage during the cleaning process. This, in turn, simplifies the cleaning task and helps in maintaining the appearance of the anodized aluminum, whether it has a Gold Anodized finish or another color achieved through the use of LW-22 as an Anodizing Agent in the Aluminium Anodizing Process.
