Aluminum Alloy Trivalent Chromium Passivator AL-100

AL-100 Aluminum Alloy Trivalent Chromium Passivator

1. Properties

1. concentrated liquid

2. for trivalent chromium passivation of aluminum

3. Its anti-corrosion performance is superior to six valence chromium passivation.

4. can also be used for aluminum alloy and aluminum casting.

5. also can be used for the pretreatment of paint, powder coating and sizing processing.

6. It is easy to operate for immersion, spray, hand wipe.

7. formed a transparent, light colored coating.

8. low contact resistance, less than 0.8 mOhm/cm².

9. can be resistant to the high temperature of 100 centigrade degree without detracting from its corrosion resistance ability

10. environmental protection, safe non-toxic, simple operation and wastewater treatment.

11. meet or exceed the MIL-DTL-81706 and MIL5541 corrosion standard (according to ASTMB-117 and DIN 50021 SS neutral salt spray test standard Quasi, more than 336 hours to appear white rust)

2. Technological 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

Note:

1. The film with AL-100 treatment can be carried out immediately a coating process after drying. It is better for coating process to place 24 hours after passivation.

2. Maintenance: adjust the concentration and pH to the best state according to regular analysis.

3, Consumption: The consumption almost only depends on the carrying amount. Every 1m² product (including carrying amount), need to add a concentrated solution of 15-25ml.
