Braycote 803, 1lb U6 NM0005-2051 15B1D7 / 25019-AEJR|
Castrol Braycote 803
Perfluoroether Grease Wide
Temperature, Low Volatility
Castrol Braycote 803 is a smooth,
buttery, translucent-white, NLGI #2, grease, based on perfluoropolyether oil
and thickened with a tetrafluoroethylene gelling agent. This product provides
excellent lubricity, oxidative and thermal stability, low volatility, good
shear stability, low acute toxicity and contain no sodium or other alkali metal
containing ingredients. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can
be used to clean this product. Refer to the data sheets for information
regarding these products.
Braycote 803 was developed for use in
applications where long term exposure to high temperature or high vacuum is
expected. This product is fully compatible for use in both direct and indirect
contact with liquid and gaseous oxygen (LOX/GOX). Braycote 803 is stable with
exposure to strong acids and oxidizers. Perfluorinated greases, in general,
exhibit excellent shelf lives due to their intrinsic inertness.
Below -62ºC to above 260ºC (below -80ºF
to above 499ºF). Lower temperature operation below -62ºC (-80ºF) is possible
where adequate torque is available.
Braycote 803 is compatible with most commonly
used construction materials including metals, plastics and elastomers. This
product 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 Braycote 803 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.
Braycote 803 is available in 2 oz
(AVDP) disposable syringes, 1 lb plastic jars (NGLI Grade 2). A specially
filtered “Micronic” version of NGLI Grade 2 is also available in 2 oz (AVDP)
disposable plastic syringes and 1 pound jars.
