Braycote® 600 EF Vacuum Grease

Product Data Sheet


Description:
Castrol Braycote® 600 EF is a smooth, buttery, translucent off-while colored NLGI #2 grease. Castrol Braycote® 600 EF uses Castrol Brayco® 815Z as the base fluid and a tetrafluoroethylene telomer as the gelling agent. This grease is nonflammable, chemically inert and thermally stable and does not use any chlorofluorocarbons (CFC's) during product manufacture. It has exceptionally low volatility and has little tendency to form deposits. It has excellent lubricating properties, good shear stability and low acute toxicity. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can be used to remove this lubricant. Refer to the data sheets for Castrol Fluoroclean™ X100 and Castrol Fluoroclean™ HE for information regarding these products.

Temperature Range:
-80°C TO 204°C (-112°F TO 400°F)

Uses:
Braycote® 600 EF is designed to operate in the presence of fuels, oxidizers, and in applications of deep space vacuum. It is used in gears, ball and roller bearings, electrical contacts, and "O" rings. This grease is highly recommended for applications where temperature extremes and/or low vacuums are routine, such as cryogenic coolers, FLIR., laser optical systems, or hostile chemical environments. Perfluorinated greases, such as Castrol Braycote® 600 EF exhibit excellent shelf life due to their intrinsic inertness.

Limitations:
Castrol Braycote® 600 EF is compatible with most commonly utilized materials, plastics and elastomers. Castrol Braycote® 600 EF 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 Braycote® 600 EF 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.

Packaging:
Castrol Braycote® 600 EF is packaged in 2 oz (AVDP) disposable polypropylene syringes and 1 pound jars by Castrol and some is repackaged by SPI Supplies into 10g syringes.
