SURTEC® 650
Cr6+ free passivation of aluminum
As an alternative to the Cr6+ containing Alodine 1200 Mifa Surface Treatment offers the Cr6+ free passivation Surtec® 650. Through the chromating process a chromate layer (conversion layer) is formed onto a metal surface.
The chromating process converts the aluminium base layer into another aluminum connection. This thin conversion layer protects the substrate against corrosion and is an excellent basis for the application of various types of lacquering and paintings. After lacquering the chromate layer gives a perfect and long lasting protection against undercorrosion.
Mifa Surface Treatment offers yellow chromating (Alodine 1200) as well as the Cr6+ free passiviation of Aluminum, Surtec® 650.
