Braycote 600 EF

Castrol Braycote 600 EF

Braycote 600 EF Description:

Castrol Braycote 600 EF is a smooth, buttery, translucent off-white colored, NLGI #2 grease. 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 manufacturing. Braycote 600 EF 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.

Castrol Braycote 600 EF

Braycote 600 EF Temperature Range:
-80C to 204C (-112F to 400F)

Braycote 600 EF Uses:
Braycote 600 EF is designed to operate in the presence of fuels, oxidizers, and in applications of deep space vacuum. Braycote 600 EF is used in gears, ball and roller bearings, electrical contacts, and "O" rings. Braycote 600 EF 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.

Braycote 600 EF Shelf Life:
Perfluorinated greases, such as, Braycote 600 EF exhibit excellent shelf life due to their intrinsic inertness.
