The lubricant covered by this specification is intended primarily for use in liquid oxygen systems, space vehicles, bearing assemblies, and other equipment where the environments of extreme temperature and nuclear radiation preclude the use of commercial lubricants and organic solid film lubricant. It is intended to reduce wear and to prevent galling and seizing of metal surfaces. Do not use the lubricant on materials that may be adversely affected by exposure to the specific cure temperature of 150 °C. The lubricant should not be used with oils or greases, unless field use indicates otherwise.
