Commercial form: fine granules
Chemical character: Azo-dyestuff, unmetallized
Density: 800 g/l
Solubility in water: 50 g/l at 20°C
Storage stability: practically unlimited, in closed original containers
Ecotoxicological data: see safety data sheet.
2. Application conditions
Concentration, dyeing temperature and time
Concentration Dyeing temperature Dyeing time
Bright shades 0,05 - 0,2 g/l 25 - 60°C 10 - 20 min
Medium shades 0,3 - 0,8 g/l 25 - 60°C 10 - 20 min
Dark shades 1,0 - 4,0 g/l 25 - 60°C 20 - 30 min
pH: 5,5 ± 0,5
Buffer: The dyebaths are preferably buffered with
8 g/l sodium acetate trihydrate
+ 0,4 ml/l acetic acid for pH 5.6
Water quality: preferably deionized
Sealing: preferably with Anodal® ASL (one or two stage).
3. Setting the Dyebath
When setting the dyebath, care must be taken that the dyestuff is well dissolved. Dissolve the
dye preferably with hot water (80°C) in a separate container (approx. 5 parts water to 1 part
dye). Then this mother solution will be added to the dyebath while stirring.
4. Lightfastness of the Dyeings
Lightfastness of dark dyeings (12 µm): Note 7 (ISO 2135).
5. Special remarks
- All purpose dye of low sensitivity, widely used for shading gold tones.
- Unsealed dyeing can be skipped with nitric acid.
- Prevention of mould formation
An addition of an antimicrobial product can inhibit mould formation for a long time.
We recommend the addition of Nipacide CI 15 (See Technical Information) 25 – 50 mg/l.
6. Disposal of the dyebaths
Spent dyebaths can be readily precipitated with Anodal® WT-1 Liquid. The method is
described in detail in the Technical Information bulletin for Anodal® WT-1 Liquid.
