For parts that are sulfuric acid anodized, AnoBlack EC provides electrolytic blackening using inorganic metallic salts as opposed to organic dyes. The result: a 100% smut-free coating that will not fade under extremes of either light or temperature.
AnoBlack EC coatings exceed the requirements of MIL-A-8625 Type II, Class 2 coatings. It has been approved by major aerospace OEMs for space vehicle applications where emissivity and high- temperature performance are critical.
❖ Anoplate’s AnoBlack EC is proven for 1000, 5000 and 6000 series aluminum. It will not work with 2000 or 7000 series aluminum. Welded components should use identical welding rod material to ensure complete coverage.
❖ Like all anodize coatings, this coating penetrates into the surface and grows up from the original dimension. A dimensional change of 0.0002 – 0.0003” per surface is common for 6000 series alloys. Other alloys could see different dimensional growth than what is typical.
❖ No outgassing when compare to conventional Type II anodize, or optical paints
❖ Able to withstand extremes of temperature without color degradation
❖ Unlike some optical pains, AnoBlack EC can be applied to exacting tolerances.
❖ Flat optical performance throughout visible to infrared ranges (VIS/IR) – no peaks at certain wavelengths.
❖ Optical applications using either ultraviolet or infrared light in which the black color must not bleach or fade.
❖ Medical devices that are subject to heat and/or aggressive cleaning agents needed for sterilization.
❖ Semiconductor manufacturing and other applications which require zero particulate generation.
❖ Any application where parts are subjected to intense light-such as space vehicle cooling units, external components, and light sinks.
❖ On 6000 series aluminum, will withstand 500oF for 1 hour without optical degradation
❖ Total normal emittance after 500oF bake is >0.90
❖ RoHS Compliant
