Product Introduction
Aluminum Alloy Casting Trivalent Chromium Passivator  Phoenix Al 100
Property

AL-100


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
