Castrol Braycote 803 EP

Grease, Wide Temperature, Hard Vacuum High Load Carrying

Description

Castrol Braycote® 803EP is a smooth, buttery, grayish colored NLGI #2 grease, based on a perfluoropolyether oil (Castrol Brayco® 812) and thickened with a tetrafluoroethylene gelling agent. It also contains an extreme pressure additive. This product is thermally stable in air, vacuum, or in the presence of oxidizers such as oxygen and does not polymerize under these conditions. This grease is designed to operate from below -65ºF to above 500ºF (below -54ºC to above 260ºC) due to its inherently good volatility characteristics. Castrol Braycote® 803EP is compatible with all commonly used construction materials including metals, plastics and elastomers. Castrol Fluoroclean™ X100 or Castrol Fluoroclean ™ HE can be used to clean this product. Refer to the data sheets for information regarding these products.

Application

Castrol Braycote® 803EP was developed for those applications in which long- term exposure to high temperature and hard vacuum are expected and high load carrying capabilities are required. This product is stable with exposure to strong acids and oxidizers. Perfluorinated greases, in general, exhibit excellent shelf lives due to their intrinsic inertness.

Additional Information

Temperature Range

Below -54 ºC to above 260 ºC (Below -65 ºF to above 500 ºF).

Compatibility

Castrol Braycote® 803EP is compatible with most commonly used construction materials including metals, plastics and elastomers. It may be adversely affected by Lewis Acids such as aluminum chloride, at elevated temperatures. Newly exposed rubbing surfaces of aluminum, magnesium or titanium alloys at elevated temperatures may react with Castrol Braycote® 803EP under certain conditions. Such systems should be thoroughly evaluated. Surfaces must be well cleaned of organic rust inhibitors prior to grease application to ensure proper lubrication.

Packaging

Castrol Braycote® 803EP is available in one pound jars and 10 gram syringes.
