Dye time: Depending on the shade desired, dye times could range from 2-15 minutes, but can only be determined by sampling in plant production.
Preferred sealing:
- Specialty Sealant MTL
- Specialty Sealant
- Conditions For Using Specialty Green SG-S
- Tank: Stainless steel or other acid resistant materials such as neoprene, polyethylene and polypropylene that can withstand a constant operating temperature of 140°F.
- 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: Moderate 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. Idle solutions: For consistent shades of green, continuous agitation is required.
- Light Fastness
- Rating: 7 (1=poor, 8=excellent)
- This color is not recommended for outdoor applications or other situations where it is subjected to intense UV radiation.
- 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 (160-180°F) 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, 140°F ±5°F.
- Conversion Factor
- Converting grams per liter (g/l) to ounces per gallon (oz/gal)
- g/l x 0.134 = oz/gal
- Dyebath Concentration Determination
Dyebath concentration can only be determined by spectrophotometric analysis. Full instructions are available upon request.
