agent for aluminium anodising

LW-99 Nickel-free and Fluoride-free Medium Temperature Sealing Additive is a kind of colorless or light amber transparent liquid which has excellent sealing effect for aluminum oxidation film. It does not contain heavy metals, which not only will solve the problems caused by heavy metal in waste water treatment process, but also can avoid aluminum surface greenish phenomenon which caused by the oxide film absorbing nickel salt during the sealing period. LW-99 is applicable to the transparent film, polishing, electrolytic coloring film sealing and it has the advantages of simple operation, environmental protection, water-saving, free of treatment to fluoride and nickel irons in waste water processing which can be cost-saving.

LW-08 Cold Sealing Additive is a light green solid powder which has stable sealing quality as well as the following characteristics: 1. The solution has excellent resistance to impurities. 2. Wider operating range: temperature required to 20-35℃, even at 15℃ can achieve good sealing effect if extend the sealing time; running water can be used for bath make-up. 3. Easy to operate: The solution is of good buffering capacity to acid and alkali. It’s no need to adjust the PH frequently. And the consumption of F- and Ni2+ keeps good balance. 4. Excellent capacity of anti-sealing bloom. 5. Silver white aluminum profiles can keep color well after sealing.

LW-10 Medium Temperature Sealing Additive is a reddish brown to brown liquid which is for aluminum profiles oxidation film sealing treatment, the sealing quality is stable and of wide application range, the profile surface texture is superior after sealing treatment.

LW-50 Medium Temperature Sealing Additive is a light green powder which is for aluminum profiles oxidation film sealing treatment.
