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.

Abrasion resistance	moderate	light	moderate	moderate	moderate	moderate	light
Adhesion	Coated pieces withstand scotch tape test (3M853 Crystal Clear tape, strength of 13N per 25mm), without any evidence of coating removal.
Outgassing:
1. CVCM (%)	0.001
2. RML (%)	0.2
Chemical content	completely inorganic
Surface resistivity	≤2X106Ω/□
Cleanability	Coated pieces withstand cleaning with ethanol, IPA or acetone with no change in optical and technical characteristics. Magic Black™, Metal Velvet™ and Litho Black™  should be cleaned very gently.

* Ultra Black can be provided on planar parts only
** Metal Velvet can be provided only as roll/ sheet material
