Etching aluminum is an important step in the anodising process. Etching includes cleaning the aluminum surface, removing all alloy metals that could create interference during the anodising stage.
The cleaning process also removes contaminants from the metal surface, such as oils. BONDERITE® strong alkaline liquid products are developed specifically for aluminum to create different finishes from semi gloss to E6 matt.
BONDERITE® etching aluminum products can be applied using immersion. Etching includes cleaning the aluminum surface, removing all alloy metals that could create interference during the anodising stage, as well as contaminants such as oils and fats.
In addition and within the treatment time, it is possible to achieve different grades to create the required aesthetic. Based on its etching experience, Henkel has developed specific etching products for aluminum that deliver greater advantages compared with traditional products. The high level of aluminum in the solution ensures a high-quality surface finish.
BONDERITE® etching aluminum products have high environmental credentials: High aluminum dissolution during the process reduces sludge in the wastewater, saving costs in wastewater management and reducing water consumption. Additionally, high aluminum dissolution reduces product consumption and increases cost savings.
A wide range of operational conditions guarantees high quality for all kinds of Al alloys. BONDERITE® etching aluminum solutions are available in liquid form with automatic dosing equipment, which makes life easy for workers, increasing safety and keeping them healthy.
