Aluminum alloy passivation liquid
Product overview:
Aluminum alloy passivation liquid can form a layer on the aluminum surface in time The uniform passivation film with strong protective performance can be used for anti-corrosion treatment of aluminum alloys and aluminum die-castings to form a transparent, light-colored coating on the surface. It can also be used as a pre-treatment for spraying, powder coating and gluing. The product does not contain hexavalent chromium, is environmentally friendly, safe and non-toxic, has simple operation and wastewater treatment and low unit cost.
Second product advantage:
. Suitable for non-hexavalent chromium passivation of aluminum materials. The concentrated liquid based on trivalent chromium has better anti-corrosion properties than the hexavalent chromium passivation process.
. It can be used as a post-treatment after anodizing to form a transparent and light-colored coating on the surface of the workpiece.
. Ultra-long anti-salt spray and anti-rust performance (according to - and neutral salt spray test standards and above, initial white rust will begin to form, but the anti-corrosion effect may vary due to different material characteristics).
. It is easy to operate in soaking, spraying and manual wiping processes. It is environmentally friendly, safe and non-toxic, and has simple operation and wastewater treatment.
Three recommended uses:
. Suitable for passivation and anti-rust treatment of aluminum, aluminum alloys and aluminum die-castings. It can also be used for pre-treatment of spraying, powder spraying and gluing.
. Widely used in mobile communications, aerospace, automotive parts, electrical and electronic equipment, waveguide equipment, navigation industry, precision instruments, etc.
Four environmental protection properties:
. Passivation liquid does not contain harmful substances The material complies with environmental protection regulations and has passed other tests.
. Wastewater is treated in a centralized manner and neutralized with alkaline lime water or sodium hydroxide to make the value close to the value before being discharged, which will have no impact on the environment.
5. Packaging and storage:
. This product is packaged in plastic barrels (kg/barrel).
. Store in a ventilated, cool and dry place. The storage temperature does not exceed ℃ and avoid direct sunlight. The validity period is 3 months.
