SANODURE ORANGE RL
Sanodure® Orange RL
Homogeneous, water soluble dyestuff for the adsorptive dyeing of anodised aluminium.
The main applications for Sanodure® Orange RL are:
Only recommended for interior use.
1. Dye-specific Data
Commercial form: fine granules
Chemical character: Azo-dyestuff, unmetallized
Bulking volume: 700 g/l
Solubility in water: 40 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 - 3.0 g/l 25 - 60°C 20 - 40 min
pH-value: 6,0 +/- 0,5
Water quality: preferably deionised
Sealing: preferably with Anodal® ASL(one or two stage sealing).
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 5-6 (ISO 2135).
5. Special remarks
- The dyestuff dyes very extensively.
- Unsealed dyeings are virtually unstrippable in diluted nitric or sulphuric acid.
They can be stripped in nitric acid 10 % + potassium permanganate 5 %.
After the treatment in Potassium permanganate, neutralization must be carried out for 1-5 min
in a sodium bisulphite 5 % solution.
- The dyebaths are sensitive to aluminium; anodized objects should therefore be
rinsed thoroughly before dyeing.
- 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.
The table below shows the additions required for precipitating Sanodure® Orange RL.
