Evaluation of Reformulated Thermal Control Coatings in a Simulated Space Environment
Abstract
The Air Force Space and Missile Systems Center and Wright Laboratory Materials Directorate (WL/ML) sponsored an effort to reformulate and qualify Illinois Institute of Technology Research Institute (IITRI) spacecraft thermal control coatings. S13G/LO-1, Z-93, and YB-71 coatings were reformulated by IITRI because the potassium silicate binder, Sylvania PS-7, used in the coatings is no longer manufactured. Coatings utilizing the binder's replacement candidate, Kasil 2130, manufactured by The Philadelphia Quartz (PQ) Corporation, Baltimore, Maryland, were tested at the Materials Directorate's Space Combined Effects Primary Test and Research Equipment (SCEPTRE) Facility operated by the University of Dayton Research Institute (UDRI). The SCEPTRE Facility's simulated space environment consists of combined ultraviolet (UV) and electron exposure with in situ specimen reflectance measurements. A brief description of the effort at IITRI, a brief description of the SCEPTRE Facility, results and discussion from testing of the reformulated YB-71, S13G/LO-1, and Z-93 coatings in SCEPTRE and other organizations are presented.
