Metaldye Orange AGN

Metaldye Orange AGN is azo dye (metal complex) having all round fastness. This dye basically used for Jewellery. This is unsuitable for exterior building elements.




Physical Form: Dry Powder
Appearance: Dark Orange Powder
Chemical Class: Metalized  azo dye
Light fastness: Good
Heat fastness: Good


Applicable condition are as:


Coating thickness: 15 - 25  microns
Concentration: 3 - 4 g/l
Temperatures: 55° - 60° C
pH range: 5.5 +- 0.5
Buffering: the bath must be buffered with 8 g/l sodium acetate tri hydrate 0.4 ml/l acetic acid for pH 5.5
Time: 10 - 15 minutes
Water Quality: preferably de–ionized; dyeing is also possible in tap water, but this can reduce the service life of dye bath




The dyed oxide film must be properly sealed properly using a hot sealing product, from ALFISEAL products range, for best result.

Other Recommendation:

1) Ammonium compounds shall not be used for controlling of the pH or to buffer dye bath solution.

2) The presence of ammonium compounds in the sealing solution may cause leaching and loss of color.

3) Use sodium acetate for dye buffer.

4) Adequate care to be taken for proper rinsing to control drag-in for optimum tank life.

5) Dye may be dissolved separately outside the dye bath. Use demineralized water for better dye bath stability.

6)  The life of dye bath is reduced by water containing ammonium.
