Nickel-free and Fluoride-free Medium Temperature Sealing Additive

LW-99 Nickel-free and Fluoride-free Medium Temperature Sealing Additive is a remarkable colorless or light amber transparent liquid. In the Aluminium Anodizing Process, it serves as an Anodizing Agent with an excellent sealing effect for the aluminum oxidation film.

As a Medium Temperature Sealing Additive, LW-99 stands out due to its unique properties. It does not contain heavy metals, which effectively addresses the issues associated with heavy metals in the wastewater treatment process. Additionally, it prevents the aluminum surface from turning greenish, a problem that can occur when the oxide film absorbs nickel salt during the sealing period. This additive is suitable for sealing transparent films, polished surfaces, and electrolytic coloring films.

One of the significant advantages of LW-99 is its simplicity of operation. It is also environmentally friendly, contributing to water-saving efforts. Moreover, since it does not require the treatment of fluoride and nickel ions in wastewater processing, it helps in cost savings.

The features of Aluminum Sealing Additive LW-99 are quite impressive. It is environmentally friendly, being free of nickel, fluoride, and heavy metals. It exhibits high corrosion resistance and strong light resistance, ensuring the durability of the sealed aluminum products. The fact that it is odorless makes it more pleasant to work with. Additionally, it is an innovative product in China, marking the beginning of a new era for nickel-free and fluoride-free sealing products. The stability of LW-99 is also remarkable, as environmental aging tests have shown that profiles sealed with it maintain a very stable appearance (with almost no change) even after being exposed to the hot sun for several years.

After the anodizing and sealing processes are completed, when it comes to Cleaning Anodized Aluminum, the properties of LW-99 can have a positive impact. Its high corrosion resistance and stability mean that the anodized surface is less likely to accumulate dirt or be damaged, making the cleaning process more straightforward. Overall, LW-99 Nickel-free and Fluoride-free Medium Temperature Sealing Additive, as an Anodizing Agent, plays a crucial role in the Aluminium Anodizing Process and also facilitates the subsequent cleaning of anodized aluminum with its beneficial features.
