TMJ-850-LSY Yellow Paint/Coating for Logos and Emblems on Spacecraft

Above TMJ-850-LSY sample stayed the same color after 4 years of space exposure on MISSE

TMJ-850-LSY is an organic yellow paint developed for use on spacecraft and satellite EVA handrails and Beta cloth utilized in the manufacture of MLI blankets.  If the Beta cloth is Teflon coated, the surface should be prepared with a suitable etchant prior to coating application for best results. A specialized pigment in a silicone binder, AMJ-850-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. TMJ-850-LSY meets flammability and toxicity requirements of NHB 8060.1C.  TMJ-850-LSY has been tested and approved for use on Space Station hardware by NASA MSFC.  The results of these tests were as follows: Total Mass Loss (TML) of 0.05%, Collected Volatile Condensable Material (CVCM) of 0.01% and Water Vapor Recovery (WVR) of 0.01%.

TMJ-850-LSY has been thoroughly tested in space, having been flown on the Materials International Space Station Experiment (MISSE).
