Optical Black Coating

Acktar is a world leader in high emissivity coatings.  Black Coatings with extremely high absorptance for optics, electronics and space applications are available now.
The combination of a very low reflectance, high thermal stability, excellent adhesion, and low outgassing - in a coating only microns thick - is unique to Acktar.
