Solid Alkaline Etching Additive

Anodizing Agent, it plays a crucial role in the Aluminium Anodizing Process. In this process, the alkaline etching step, for which LW-02 serves as an aluminum etchant, is a key phase in the surface treatment of building aluminum profiles. The primary purpose of alkaline etching is to eliminate the natural oxide film on the surface of the aluminum material and activate the surface for anodic oxidation. However, improper control of the alkali etching solution can lead to issues such as uneven alkali etching quality. If the amount of additives is insufficient or the wrong additives are used, the bath liquid may produce a significant amount of precipitation and form scale, which needs to be removed. This is where LW-02 shines. By using LW-02 Alkaline Etching Additive, the formation of scale can be avoided, and the aluminium dissolution can reach over 120g/L. This additive, acting as a Basic Etching Agent, not only improves the surface quality of the aluminium profile but also reduces the a…
