Description
Castrol Brayco™ 1625 is a clear water-white perfluoroether oil. It is odorless, non-flammable and generally chemically
inert. It exhibits good thermal stability, is compatible with most commonly used propellants, fuels and oxidizers, and
virtually unaffected by high gamma radiation doses. Other characteristics include excellent lubricating properties, good
dielectric properties, excellent shear stability and a low order of acute toxicity. Castrol Fluoroclean™X100 can be used to
remove this lubricant. Refer to the data sheet for Fluoroclean X100 for information regarding this product
Application
Brayco 1625 is an excellent lubricating oil for precision bearings. It can also be utilized as a damping fluid, flotation fluid
and as a lubricant for electrical contacts. Perfluorinated fluids, in general, exhibit excellent shelf lives due to their intrinsic
inertness
Additional Information
Temperature Range
-30ºC to 204ºC (-22ºF to 400ºF)
Limitations
Brayco 1625 is compatible with all commonly utilized materials, plastics and elastomers. It is very slightly soluble in most
organic solvents and materials other than highly fluorinated solvents. Lewis Acids such as AlCl3 can adversely affect
Brayco 1625 at elevated temperatures. Newly exposed rubbing surfaces of aluminum, titanium and magnesium may react
with this product under certain conditions. Such systems should be thoroughly evaluated. Surfaces must be free of organic
rust inhibitors prior to grease application to insure proper lubrication.
