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.
Temperature Range
-72ºC to above 204ºC (-100ºF to 400ºF) under normal operating conditions and up to
260ºC (500ºF) for brief periods.
Uses
Castrol 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.
Limitations
Castrol Brayco® 815Z is compatible with all commonly utilized materials, plastics, and
elastomers. It may be adversely affected by Lewis Acid Catalysts such as aluminum
chloride at elevated temperatures. Newly exposed rubbing surfaces of aluminum,
magnesium, or titanium alloys may react with this product under certain conditions.
Such systems should be thoroughly evaluated. Surfaces must be well cleaned of
organic rust inhibitors prior to oil application to ensure proper lubrication.
Packaging
Castrol Brayco® 815Z is packaged in 2 ounce (AVDP) bottles and in 1 pound jars. A
specially prepared "Micronic" grade - ultra filtered - is available on request.
