Braycote 296Sub-Micronic, Extreme Low Volatility Grease
Braycote 296 Description
Castrol Braycote™ 296 (previously called Microcote™ 296) is smooth, off-white colored perfluoropolyether grease, in NLGI grade 2.
Braycote 296 uses a proprietary base fluid thickened with a special tetrafluoroethylene gelling agent.
Braycote 296 is specially formulated to provide wear protection in most load and speed conditions under high or extreme vacuum conditions.
Braycote 296 offers excellent lubricity, thermal stability, low volatility, good shear stability, low acute toxicity and contains no sodium or other alkali metal containing ingredients.
Braycote 296 is nonflammable and chemically inert. Castrol Brayco™ IC X-100 (previously called Fluoroclean™ X100) can be used to remove these lubricants. Refer to the data sheets for information regarding this product..
Braycote 296 Uses
Braycote 296 is designed for use in extreme high vacuum critical particle count conditions which require antiwear lubrication.
Typical applications include robotics used for semi-conductor production and other electronic applications. Braycote 296 grease can be used to lubricate bearings, gyros, gears, and also as an assembly lubricant for O-rings and elastomers. Temperature Range: -50ºC to 204ºC (-58ºF to 400ºF)
Braycote 296 Typical Properties
Braycote 296 Limitations
Braycote 296 is compatible with most commonly utilized metals, plastics and elastomers. These products, such as aluminum chloride, may be adversely affected by Lewis Acids at elevated temperatures. Newly exposed rubbing surfaces of aluminum, titanium, or magnesium alloys, under certain conditions, may react with Braycote 296. Such systems should be thoroughly evaluated. Surfaces must be well cleaned of organic rust inhibitors prior to grease application to insure proper lubrication. Packaging: Braycote 296 is available in 2 ounce (AVDP) syringes, 1.75 pounds jar and in 1 pound jars. This product was previously called Microcote 296. The name was changed in 2015 Braycote™
