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.
