TMS-800-IY is an inorganic yellow paint developed for use on spacecraft and satellite EVA handrails and for 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. This material has good adhesion on hard anodized aluminum. A specialized pigment in a silicate binder, TMS-800-IY can be spray deposited with an air brush or high-volume low-pressure system to form a flexible inorganic yellow nonspecular marker coating for use on emblems, logos, signs etc. TMS-800-IY meets flammability and toxicity requirements of NHB 8060.1C.
TMS-800-IY has been thoroughly tested in space, having been flown on the Optical Properties Monitor (OPM), the MIR MEEP POSA-I experiment and the Materials International Space Station Experiment (MISSE).
