AMJ-700-IBU is an inorganic blue paint developed for use on spacecraft and satellites. A specialized pigment in a silicate binder, AMJ-700-IBU can be spray deposited with standard air spray painting equipment or high-volume low-pressure system to form a bendable inorganic nonspecular blue marker coating for use on emblems, logos, and signs on spacecraft / satellites. NASA has tested AMJ-700-IBU exposed to atomic oxygen (AO) fluence of 5.6 x 1022 atoms/cm2 and vacuum ultraviolet (VUV) energy. It has also be tested for resistance to ultraviolet (UV) radiation for a duration of 566 equivalent solar hours. Less than 2% deterioration in solar absorptance (α_s) and less than 1% change in thermal emittance (ε_t). AMJ-700-IBU will be tested in the near future for flammability and toxicity requirements per NHB 8060.1C and being completely inorganic this coating is expected to pass these tests.
This spacecraft / satellite paint has been thoroughly tested in space, having been flown on the Materials International Space Station Experiment (MISSE). AZ Technology used AMJ-700-IBU in coating all NASA logos (and ESA logos) currently on the International Space Station (view image at lower left).
