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 dyebaths are sensitive to sulphate and aluminium; anodized objects should therefore be rinsed thoroughly before dyeing.
• The best dyebath stability is achieved by :- cold dyeing (20 – 25 °C)- a pH not below 5,5 in buffered medium 8g/L Sodium Acetate/ 0.4mL  acetic acid (100%)- a high dye concentration (1 – 3 g/l)
• Water sealing lightens the dyeing and it becomes slightly yellower.

 

Prevention of mould formation:

An addition of an antimicrobial product can inhibit mould formation  if you need to store the product for extended time. We recommend the addition of our Preservative B at a preservative level of 1-2 drops/l.
