LW-23 New type Black Electrolytic Coloring Additive represents the latest scientific breakthrough of our company. In recent times, with the persistently high price of stannous sulfate leading to a sharp increase in the cost of tin salt electrolytic coloring, Haihua Technology Company has strategically launched LW-23 New type Electrolytic Coloring Agent. After nearly two years of dedicated research and development, along with large-scale production verification, it has proven to be capable of completely replacing and outperforming the stannous sulfate electrolytic black coloring production process, thus significantly slashing production costs.
As an Anodizing Agent, this product is well-suited for the anodizing electrolytic black coloring process of solar photovoltaic aluminum brackets and architectural aluminum materials within the Aluminium Anodizing Process. LW-23 Black Electrolytic Coloring Agent exhibits excellent dispersion and complexation properties. It effectively addresses the edge effect of current, commonly known as the "photo frame phenomenon." The stability of the bath liquid ensures uniform coloring, a rich and positive blackness, and good reproducibility, all of which contribute to high-quality results in the anodizing process
After the anodizing and coloring processes are completed, when it comes to Cleaning Anodized Aluminum, the qualities of LW-23 play a beneficial role. Its ability to provide a stable and uniform coloring means that the anodized and colored surface is less likely to have irregularities or residues that could complicate the cleaning process. In contrast to similar products on the market, LW-23 offers distinct advantages. It boasts a full blackness with the flexibility to freely adjust the base color, without the issue of film bursting. The resulting shiny oily black appearance is aesthetically pleasing.
Moreover, its long-term stability eliminates the need for frequent bath liquid updates. Its good dispersibility ensures there is no photo frame effect and no redness at the end of the base color. In comparison, similar products often have a reddish base color, require secondary electrolysis of tin salt which pollutes the tin salt electrolytic bath, suffer from the common problem of film explosion, are gray and thin with poor stability, and necessitate frequent bath updates. They are also prone to color differences and dispersion issues, and in severe cases, can exhibit a photo frame effect. Overall, LW-23 is a superior choice for the Aluminium Anodizing Process, facilitating both the coloring and subsequent cleaning of anodized aluminum with its capabilities as an Anodizing Agent.
