ABSTRACT:
Spacecraft components having critical surfaces which must arrive in outer space in a contamination-free, pristine state to assure their effecient operation over the entire spacecraft mission life are protected against contamination by applying to the surfaces a protective coating which sublimes away when exposed to the outer space environment, thereby exposing the surfaces in their pristine state to the environment.
