Violet 3D Anodizing Dye
1.Description
Specialty Violet 3D is a single component, water soluble dye, used to color anodized aluminum vivid shades of violet, similar to the African violet plant.
Eco-friendly, contains no heavy metals.
RoHS compliant
REACH compliant
2.Application instructions
Concentration: 1-3 g/l
pH: 6.0 ±0.5
Buffering: Not required
Temperature: 140°F ±5°F / 60°C ±-1.5°C
Oxide film thickness: 0.30-0.50 mils.
Dye time: Depending on the shade desired, dye times could range from 2-10 minutes, but can only be determined by sampling in plant production.
Preferred sealing: Caswell Sealant MTS
3.Conditions for using Specialty Violet 3D
Tank: Stainless steel or other acid resistant materials such as neoprene, polyethylene and polypropylene that can withstand a constant operating temperature of 60°C.
Water quality: Deionized
pH adjustments: Raise with sodium hydroxide.
Lower with acetic acid.
The pH should be checked once per shift with a calibrated meter and maintained within recommended range.
Bath agitation: Mild agitation must be used for high uniformity of color.
Rinsing: It is important to remove all acid residues clinging to the work and acid retention in the oxide pore itself. Rinse work load thoroughly after anodizing.
A minimum of two rinses is recommended, with the second rinse at over-flow.
To increase rinsing effectiveness, add vigorous air agitation in all rinse tanks. This also improves your rinsing of surfaces on complicated shaped parts.
4.Light fastness
Rating: 3 (1=poor, 8=excellent)
This color is not recommended for outdoor applications or other situations where it is subjected to intense UV radiation.
5.Storage
Store in original container in a cool dry location. Close package tightly after removal of dye.
In humid environments, dye powder may clump-up.
6.Preparation of a new dyebath
- A cleaned tank is filled with deionized water to about 75% of final volume and raised to dyeing temperature.
- The required amount of dye is weighed out and dissolved in hot deionized water (70-82°C) in a separate container until a slurry is formed. This is your stock solution.
- With agitation turned on in tank, pour stock solution into tank.
- Top off the tank to final working solution volume with more hot deionized water and agitate for 15 minutes.
- Using a calibrated pH meter, check the pH and adjust if necessary.
- The dyebath is brought to dyeing temperature, 60°C ±1.5°C.
7.Product safety
We recommend that the company/operator read and review the Safety Data Sheet for the appropriate health and safety warnings before use.
