PROCESS

Chromating is a chemical conversion treatment that can be applied by sprinkling or immersion. by spraying or immersion. The chromating layer is an excellent base for organic finishes. It increases the corrosion resistance of aluminium. aluminium. The intrinsic corrosion resistance is low and this treatment often requires an additional protection step This treatment often requires an additional protection step (painting, etc.). Processes used : - Attachment" coatings for small to large series.
