Abstract: The behaviors of thermal control coating in a simulated space environment are determined.The property changes of silicone thermal control coatings during the UV exposed process and electron exposed process are monitored in-situ.The property changes of different materials are compared.SEM observes the morphology of coatins.ZnO covered with K 2SiO 3 has different effects on property of coatings for both silicone rubber adhesives and silicone resin adhesives,and different bleach phenomenon is observed and its reason is discussed in briefly.
