Book Description
This paper presents an evaluation of several silicone resin binders and powdered inorganic pigments for potential use in spacecraft thermal-control paint formulations. The pigments were selected on the basis of a hypothesis relating the heat of formation of a compound to the compound's resistance to ultraviolet-radiation-induced degradation. Reflectance measurements were made in situ to determine degradatiorna tes due to ultraviolet radiation. The tested polydimethylsiloxane resins were not significantly affected by long exposures to ultraviolet radiation. All the pigments, which were dispersed in a polydimethylsiloxane resin, were degraded by ultraviolet radiation as determined by an increase of solar absorptance. For the materials evaluated in this study, no evidence was found to indicate that pigments with high heats of formation were resistant to ultraviolet degradation.
