Sanodye® Golden Orange RLW 
 
 
 
 
Homogeneous, water soluble dyestuff for the adsorptive dyeing of anodised aluminium. 
 
The main applications for Sanodye® Golden Orange RLW are:  
 
· Indoor 
· Jewellery 
 
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: 100 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: 
 
dark dyeings (12  µm): Note  5-6  (ISO 2135). 
 
5. Special remarks
- The dyestuff dyes very extensively. 
 
- Unsealed dyeings can be stripped 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. 
 
The table below shows the additions required for precipitating Sanodye® Golden Orange RLW.
