SurTec 313

Sustainable & Energy Saving Anodising Process

Energy saving due to high anodising temperature, high sulphuric acid concentration & lower voltage
Reduces maintenance cost due to a long bath lifetime
Great uniformity of the anodic coating
High aluminium concentration possible
Less cooling needed

During the anodising process the H₂SO₄ re-attacks the anodic coating. The re-attack is directly proportional to temperature and time.

SurTec 313 contains organic acids able to protect the anodic coating in two ways:

Therefore, the electrolyte temperature can be maintained higher than normal without damaging the anodic coating.

SurTec 313 also contains complexing agents that allow to work with a higher content of dissolved aluminium.

Energy savings:

Reduced managing costs and improved quality:

Lower dissolution of aluminium
Longer bath life. It's not necessary to periodically dump the anodising solution.
Improved uniformity of the anodic coating

Voltage reduction due to higher temperature

We are looking forward to your inquiry!
