Description
Castrol Brayco 815Z is a clear water white perfluorinated polyether based fluid. It is virtually inert, compatible with rocket
propellants and oxidizers, is unaffected by ultraviolet, cosmic radiation, or high vacuums. It has an exceptionally high
viscosity index and low volatility, and has little tendency to form deposits. This product is highly recommended for use in
applications at low temperature extremes and in high vacuum. It exhibits excellent lubricating properties, good dielectric
properties, excellent shear stability, and low toxicity. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can be
used to remove this lubricant. Refer to the data sheets for information regarding these products.
Application
Brayco 815Z is essentially insoluble in current fuels and oxidizers, as well as in most organic solvents. This product is
intended for use in extreme environments, and has been used successfully in many space missions and in sensitive
electronic equipment. It is particularly suited for those applications where extreme vacuums and wide temperature
variations are common. Perfluorinated fluids, in general, exhibit excellent shelf lives due to their intrinsic inertness.
