Electrolytic Black Anodizing from Anoplate from Anoplate Corporation

AnoBlack EC is an electrolytic coloring process for blackening anodized aluminum alloys. Blackening is accomplished using inorganic metallic salts (not organic dyes) and thus is 100% smut-free and will not fade under extremes of light or temperature. If your application demands rigorous coating performance, consider AnoBlack EC as an alternative to standard Type II sulfuric black anodize. Without using organic dyes, the AnoBlack EC 2-step anodize (electrolytic blackening) provides medical instruments, aerospace components and optical devices with superior, deep black color that resist corrosion and perform exceptionally well.

Key Features:

* AnoBlack EC coatings will not outgas in vacuum environment applications.
* AnoBlack EC meets MIL-A-8625, Type II, Class 2 for black sulfuric anodize and has been approved by major aerospace manufacturers for space vehicle applications where emissivity and the ability to withstand high temperatures are both critical.
* Suitable for 6000 and 7000 series aluminum Black coating is largely independent of anodic film thickness – so color depth remains consistent even on thinner coatings.

Typical Properties

AnoBlack 'EC' coatings able to withstand 500°F (240°C) for 1 hour without-any degradation. Anoplate has successfully coated 3000 and 5000 series aluminum alloys as well as 6000 and 7000 series alloys. The 'total normal emittance' of AnoBlack EC following a 500°F bake is greater than 0.90. (measurements made using Gier-Dunkle Paraboloid Spectrophotometer with a Perkin Elmer Grating Monochromator).
