Castrol Braycote® Micronic 701

Description:

Castrol Braycote Micronic 701 is a smooth, buttery, translucent, off-white, NLGI #2 grease. It uses Castrol Brayco 815Z as the base fluid and a tetrafluoroethylene telomer as the gelling agent. This product was specially formulated to provide exceptional anti-wear properties, in combination with ultra low outgassing and extreme temperature use capabilities. Braycote Micronic 701 exhibits superior chemical resistance, and is non-toxic, nonflammable, chemically inert, and does not use any chlorofluorocarbons (CFC's) during product manufacture. It has excellent lubricating properties, good shear stability, low acute toxicity, and promotes extended rolling element cycle lives. This product contains a rust and corrosion inhibitor for extra component protection. Castrol Fluoroclean™ X100 can be used to remove this lubricant. Refer to the data sheet for Fluoroclean X100 for information regarding this product.

Application:

Braycote Micronic 701 is designed to operate in the presence of fuels, oxidizers, and in applications of deep space vacuum at low temperatures. This product is recommended for use in space applications including the Space Shuttle and satellites. It should also be considered in any application where 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 Braycote Micronic 701, exhibit excellent shelf life due to their intrinsic inertness.

Temperature Range:

-80°C to 204°C (-112°F to 400°F)

Limitations:

Braycote Micronic 701 is compatible with all commonly utilized materials, plastics, and elastomers. This product may be adversely affected by Lewis Acid Catalysts, such as AlC13, at elevated temperatures. Newly exposed rubbing surfaces of aluminum, magnesium and titanium may react with Braycote Micronic 701 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.

Removal of unwanted grease from grease applied surfaces:

The composition of this product is a mixture of small PTFE particles (which won't dissolve in anything) and a perfluorinated polyether liquid. We have found that Castrol^® Fluoroclean™ HE is an effective solvent for the liquid component of the formulated composition and aids in the removal of the grease from places where it is no longer needed or wanted.
