Typical Properties

nano black coating reflectance chart

Nano Black is applied for thermal passive management (space and other), wafer-level optics, and highly precise instrumentation like atomic clocks.

In addition to its unique optical performance, Nano Black delivers many other attributes important in space applications:

Low outgassing
Operating temperatures from (-)70°C to (+)200°C
No particulation
The coating thickness ≤ 1.5 µm

Adhesion

Metals, glass, ceramics, polymers

Adhesion test (ref ECSS-Q-ST-13C)

Coated pieces withstand scotch tape test (3M853 Crystal Clear tape, strength of 13N per 25mm), without any evidence of coating removal.

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."
