SEALING:
The dyed oxide film must be properly sealed properly using a hot sealing salt ANO SEAL CA-350 for best result.
Other Recommendation:
- Ammonium compounds shall not be used for controlling of the pH or to buffer dye bath solution.
- The presence of ammonium compounds in the sealing solution may cause leaching and loss of color.
- Use sodium acetate for dye buffer.
- Adequate care to be taken for proper rinsing to control drag-in for optimum tank life.
- Dye may be dissolved separately outside the dye bath. Use demineralized water for better dye bath stability.
- The life of dye bath is reduced by water containing ammonium.
