A chemical conversion coating on aluminium is a process that consists of creating a protective layer against corrosion for aluminium.
We have two different systems:
- Bonderite M-CR 1200 S Aero:
Yellow in colour and with hexavalent chromium.
- Surtec 650:
Transparent and with trivalent chrome.
It is commonly used in aluminium parts that are later painted.
The conversion coat is a good mordant that enhances adherence of the primer coat on the aluminium surface.
