Product Details

This product is an additive for hard anodizing.
Anodal® EE The additive is added to the conventional sulfuric acid anodizing bath solution for hard anodizing without the need for cooling.
to 5 below °C or using high voltage.
Adding Anodal ® EE to the anodizing bath allows for both conventional and hard anodizing in the same bath. .
Anodal ® EE Advantages:
- Reduces investment in new hard anodizing equipment.
- It can be used at higher temperatures, increasing the production capacity of sulfuric acid anodizing.
- Compared to conventional anodizing processes, it can save cooling and electricity costs.
- Reduces the dissolution of the oxide film during the anodizing process.
- Reduces the impact of temperature and current density fluctuations during anodizing.
- Can achieve a smoother oxide film in normal anodizing processes.
