Aluminum alloy trivalent chromium passivator
Concentrated liquid for trivalent chromium passivation of aluminum
Its anti-corrosion performance is superior to six valence chromium passivation.
It is also be used for aluminum alloy and aluminum casting.
It can be used for the pretreatment of paint, powder coating and sizing processing.
It is easy to operate for immersion, spray, hand wipe.
It formed a transparent, light colored coating.
Low contact resistance, less than 0.8 mOhm/cm2.
It can be resistant to the high temperature of 100 centigrade degree without detracting from its corrosion resistance ability
Protect the environment, non-toxic, simple operation and wastewater treatment.
meet or exceed the MIL-DTL-81706 and MIL5541 corrosion standard (according to ASTMB-117 and DIN 50021 SS neutral salt spray test standard, more than 336 hours to appear white rust)
1. TECHNICAL PROCESS
Standard immersion technology
Aluminum alloy (silicon content <1%): alkaline degreasing → alkali erosion → descaling → immerse AL-100
Aluminum alloy (silicon content >1%): alkaline degreasing → cleaning → immerse AL-100
Standard spray process
Acidic degreasing → spray AL-100
