Castrol Brayco 815 Z Specialty Perfluorinated Fluid, Lubricating Oil, Clear White, 2 oz

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 under high vacuum. It exhibits excellent lubricating properties, good dielectric properties, excellent shear stability and low toxicity. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE may be used to remove this lubricant

APPLICATIONS
Brayco 815Z is virtually 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 applications where extreme vacuums and wide temperature variations are common. Perfluorinated fluids, in general, exhibit excellent shelf lives due to their intrinsic inertness. Temperature Range: -72ºC to above 204ºC (-100ºF to 400ºF) under normal operating conditions and up to 260ºC (500ºF) for brief periods.
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.
