Castrol Microcote® 096, 196, 296

Technical Data Sheet


Description
Castrol Microcote® 096, 196, and 296 are smooth, off-white colored perfluoropolyether greases, in NLGI grades 0, 1, and 2. Each Castrol Microcote® product uses a proprietary base fluid thickened with a special tetrafluoroethylene gelling agent with an average particle size of <0.8 microns. These products are specially formulated to provide wear protection in most load and speed conditions under high or extreme vacuum conditions. These products offer excellent lubricity, thermal stability, low volatility, good shear stability, low acute toxicity and contain no sodium or other alkali metal containing ingredients. These greases are nonflammable and chemically inert. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can be used to remove these lubricants. Refer to the data sheets for information regarding these products.

Temperature Range
-50°C to 204°C (-58°F to 400°F)

Uses
Castrol Microcote® 296 is designed for use in extreme high vacuum critical particle count conditions which require anti-wear lubrication. Typical applications include robotics used for semi-conductor production and other electronic applications. Castrol Microcote® 296 can be used to lubricate bearings, gyros, gears, and also as an assembly lubricant for O-rings and elastomers. Castrol Microcote® 096 and 196 are recommended for use in similar applications, which also require torque minimization and/or resistance to drag forces. Castrol Microcote® 096, 196, and 296 exhibit excellent shelf life.

Limitations
Castrol Microcote® 096, 196, and 296 are compatible with most commonly utilized metals, plastics and elastomers. These products may be adversely affected by Lewis Acids such as aluminum chloride, at elevated temperatures. Newly exposed rubbing surfaces of aluminum, titanium or magnesium alloys under certain conditions may react with Castrol Microcote® 096, 196, and 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
All are available in 2 ounce (AVDP) syringes or in 1 pound jars. Castrol Microcote® 196 is also available in 1.75 pound jars and Castrol Microcote® 296 is also available in 1.75 pound jars and 10 gram syringes.
