Acktar’s black coatings are manufactured using vacuum deposition technology. They are very thin, completely inorganic, have very low outgassing and low reflectivity. See our video here.

The table below provides a detailed comparison of Acktar’s black coatings with typical paint coatings.

Comparison Table

Acktar’s black coatings are typically between 3-14 µm thick, but can be tailored to between 1-30µm upon request.

No Particulation, broad working temperature range, low outgassing, thin coating with tight tolerances, low reflectivity over a wide wavelength range, high emissivity, completely inorganic, can be applied on essentially any substrate, perfect cover (no build-up) on edges.

Yes, easily! We use mechanical masking that is tailored to the requirements of the coating area.

The most common applications are: stray light absorption in UV-VIS-IR wavelengths, night vision systems, cooled Infrared detector parts, satellite parts, high surface area capacitor electrodes, LED screens and more.

Acktar is certified as a production and development facility by ISO 9001:2000, IQNet, S.A.M.S, RoHs and REACH.

In addition we are certified as a “Ship to Stock” supplier for one of the world’s largest manufacturers of IR detectors – based on our quality and strict inspection regime.

See the full list of certificates.

Acktar’s coatings are available in two options:

• 1. Direct Black Coating (current page) – where you send the part to us and we coat to your specifications.
  2. Foils and Films – Black coated foils and films with or without adhesive that can coat large areas.

The thickness tolerance of our black coatings can be as tight as 1-2 µm.

Our coatings have excellent coverage over the entire part including the ability to confirm to edges as seen in the below photo.

There is no need for special design of the edge to attain the perfect coverage.

Acktar’s Fractal BlackTM was tested by an independent laboratory to compare its performance at very low temperatures with that of thick epoxy layers and black paint.

The summary of the report is as follows: “The main advantage of Fractal BlackTM coating for us is the relatively high blackness at low temperatures (10K-50K) of the source of the thermal radiation achieved by small thickness of the coating.”

A full copy of the report is available upon request.

Yes, our Nano Black selective coating has high absorbance in the VIS range and low emissivity in the IR range.
