Abstract Responding to the need for dynamic outgassing testing at high temperature, ITL Inc. has developed and built an Outgassing Test Facility that accommodates the set-ups for measuring the outgassing of materials according to the ASTM E1559 test method. This paper describes the design of the outgassing system, operation of its devices and components, and presents the test results obtained on several advanced conductive and non-conductive space thermal control paints and silicones by MAP Space Corporation (France). Material outgassing tests were performed on four advanced silicone-based thermal control coatings recently developed by CNES/MAP, namely, the black PNC and mat white PCBE conductive silicone-based space paints, the white non-conductive silicone-based SG121FD paint, as well as the transparent MAPSIL® QS 1123 non-conductive silicone resin. A comparative evaluation and discussion of the outgassing test results per ASTM E1559 will be presented to prove that the MAP silicone paints do not cause contaminations on the sensitive optical coatings in the line-of-site direction by silicone-based contaminations during long-term operation in the Low Earth Orbit space environment.
