Special Remarks

    • This dyestuff dyes very extensively
    • We can’t stress enough to remove all acid residues clinging to the work and to reduce acid retention in the oxide pore itself. Rinse work pieces thoroughly after anodising. A minimum of two rinses is recommended, with the second rinse at over-flow.  The dye baths are sensitive to sulphate and aluminium; anodised objects should therefore be rinsed thoroughly before dyeing..
    • The best dye-bath stability is achieved by :- cold dyeing (20 – 25 °C)- a pH not below 5,5- a high dye concentration (1 – 3 g/l)
      • Water sealing lightens the dyeing and it becomes slightly yellowish.
      • Ammonium compounds should 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 colour.
      • Use sodium acetate for dye buffer.
      • 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 ions.
