Typical Properties

nano black coating reflectance chart

In satellites Nano Black is applied for solar thermal collectors and solar panels as well as for passive thermal management.

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

  • Essentially zero outgassing
  • Vacuum and thermal-vacuum cycling compatible
  • Operating temperatures from (-)70°C to (+)250°C
  • No particulation
  • The coating thickness is only a few microns thick
  • Compatible with virtually all substrate materials
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.
