Abstract
Ball Aerospace and Technologies Corporation (BATC) developed a unique thermal control coating named Ball InfraRed Black™ (BIRB™). The proprietary coating was developed for use on spacecraft thermal radiators, but also has application to terrestrial cryogenic and vacuum systems. The unique morphology and large effective surface area of BIRB™ generates superior cryogenic emissivity properties. Independent testing performed at NASA Goddard Spaceflight Center confirms the emissivity at 50K has been documented to be 40% greater than typical thermal control coatings, generating enhanced performance and/or substantial mass savings. The coating proves to be extremely durable and cleanable when properly handled. BIRB™ has the additional benefit of being static-dissipative, making it ideal for direct exposure to the space environment. The critical thermal, physical, and mechanical properties for BIRB™ have been measured. The coating is qualified for spaceflight, demonstrating outstanding adhesion after thermal cycling and vibration testing. Contamination control properties have been optimized, achieving low total outgassing rates as measured by testing in accordance with ASTM E1159 and demonstrating particle cleanliness meeting level 200 as defined by IEST-STD-CC1246. BIRB™ has been qualified for use on several BATC flight programs, including applications for large cryogenic radiators.
