In our subsidiary company "Alphasem", located in Switzerland, we daily use an Aluminum treatment called " Standard Ematal". I would like to use this technique here as well, but it seems that this treatment is unknown. Is it really? Characteristics:

Hi Roman,

Ematal process has been commercialized for a couple of decades in Europe and Japan. It is true that the process could not gain significant market share in the North American anodizing market. This process uses an electrolyte comprising mainly titanium salt and oxalic acid instead of sulfuric acid. Of course, the operational parameters are different those employed in conventional sulfuric acid anodizing and hardcoat anodizing.

High quality Ematal coating gives rise to a white/greyish white color, depending on alloy. If brown color occurs, it means likely that the electrolyte has become deteriorated. Since your subsidiary company has the process, you should be able to get it easily. Regards, Ling
