TMD-560-IB is an inorganic black baffle paint. With the use of a specialized mixed metal oxide pigment in a silicate binder, TMD-560-IB is an inorganic coating that can be spray deposited over complex surfaces with minimal difficulty or environmental impact to provide an inorganic nonspecular black baffle coating. This coating has not been fully tested in the rigorous environment of Low Earth Orbit (LEO), so the deleterious effects of long term exposure to the Atomic Oxygen (AO) flux found there may adversely affect the thermal and optical performance of TMD‑560-IB. However, for Geosynchronous Earth Orbit (GEO) and terrestrial applications as a baffle absorption coatingon spacecraft and satellites, TMD-560-IB provides excellent service in optical and/or thermal applications.
The table below lists the optical and application parameters of cured TMD-560-IB.
