AMJ-650-LSR Red Paint/Coating for Logos and Emblems on Spacecraft

AMJ-650 after exposure to solar radiation in Earth orbit
Above AMJ-650-LSR sample stayed the same color1 after 4 years of space exposure on MISSE.

AMJ-650-LSR is an organic red paint developed for use on spacecraft, satellites and Beta cloth utilized in the manufacture of MLI blankets.  A specialized pigment in a silicone binder, AMJ-650-LSR can be spray deposited with standard air spray painting equipment or high-volume low-pressure systems with the ease of other silicone paints to form a bendable organic red nonspecular marker coating for use on emblems, logos, signs etc. on spacecraft / satellites. AMJ-650-LSR will be tested in the near future for flammability and toxicity requirements per NHB 8060.1C.

This spacecraft / satellite paint has been thoroughly tested in space, having been flown on the Materials International Space Station Experiment (MISSE).
