Castrol Braycote® Micronic 601 EF Grease

Castrol Braycote Micronic 601 EF is a smooth, buttery, translucent, off-white, NLGI #2 grease. Its base oil (Castrol Brayco® 815Z) is a perfluorinated polyether, with exceptional chemical resistance, extremely low volatility, and a wide temperature service range. The grease is non-toxic, nonflammable, and does not use any chlorofluorocarbons (CFC's) during product manufacture. This product exhibits unusually high load-carrying capabilities as measured by the Four-Ball EP Test, and contains a rust and corrosion inhibitor for extra component protection. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can be used to remove this lubricant. Refer to the data sheets for information regarding these products.

Braycote Micronic 601 EP Uses
Braycote Micronic 601 EF is designed to operate in the presence of rocket fuels, oxidizers and high vacuum. It is frequently used in space applications including the Space Shuttle and satellites. It should also be considered in any application where a hostile chemical or extreme environmental conditions would preclude the use of an ordinary grease. Typical applications include ball and roller bearings, gears, and as an assembly lubricant for O-rings and elastomers. Perfluorinated greases, such as, this product, exhibit excellent shelf life due to their intrinsic inertness

Braycote Micronic 601 EP Typical Properties


Braycote Micronic 601 EP Temperature Range
-80ºC to 204ºC (-112ºF to 400ºF)

Braycote Micronic 601 EP Limitations
Braycote Micronic 601 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 and 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.
