LW-08 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.

Solution Maintenance: | ||
1、It is suggested to clean thoroughly the aluminum profiles before sealing process for reducing pollution of the solution. The PH of rinsing bath should not be lower than 4.5. | ||
2、Analyze the concentration of Ni2+ and F- and PH of the solution everyday. (1) Keep the concentration of Ni2+ at 0.8-1.2g/L and the concentration of F- at 0.3-0.45g/L. (2)Control the PH in the range of 6-7. If PH does not meet the technical requirement, it can be adjusted with dilute acetic acid or dilute aqua ammoniae. | ||
