Braycote 602 EF
Grease, Molybdenum Disulfide Compound,
Description
Castrol Braycote 602 EF is a smooth, buttery, grey colored NLGI #2 grease. The base fluid (Castrol Brayco® 815Z) is a
stable perfluorinated polyether with exceptional chemical resistance, extremely low volatility, and a wide temperature
service range. The gelling agent is a tetrafluoroethylene telomer. This grease contains molybdenum disulfide. This
product is nonflammable, does not use any chlorofluorocarbons (CFC's) during product manufacture, and is in general,
chemically inert. It is an excellent lubricant, has good shear stability, and low toxicity.
Application
Braycote 602 EF is designed to operate in the presence of fuels, oxidizers, and deep space vacuums. Typical
applications include ball and roller bearings, gears, electrical contacts, and as an assembly lubricant for O-rings and
elastomers. This grease is highly recommended in applications where temperature extremes and/or low vacuums are
routine. Perfluorinated greases, such as this product, exhibit excellent shelf life due to their intrinsic inertness.
Temperature Range -80ºC to 204ºC (-112ºF to 400ºF).
Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can be used to remove this lubricant. Refer to the data sheets
for these products for more information.
Limitations Braycote 602 EF is compatible with most 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 grease
application to insure proper lubrication. This product is not recommended for use in applications under high vacuum
with loads exceeding 100,000 psi for extended periods of time.
