Braycote Castrol 602EF High Vacuum Grease 10 Gram Syringe PN 05087-BA Temperature Range: -80° C/-112° F to +204° C/399° F Uses: Braycote 602EF is designed to operate in the presence of fuels, oxidizers, and deep space vacuums. Typical applications include ball and roller bearings, gears, electrical contacts, and as an assembly lubricant for O rings and elastomers. This grease is highly recommended in applications where temperature extremes and/or low vacuums are routine. Perfluorinated greases, such as Braycote 602EF exhibit excellent shelf life due to their intrinsic inertness. Braycote 602EF is a smooth, buttery, gray colored NLGI #2 grease. The base fluid (Brayco 815Z) is a stable perfluorinated polyether with exceptional chemical resistance, extremely low volatility, and a wide temperature service range. The gelling agent is a tetrafluoroethylene telomer. This grease contains molybdenum disulfide. Braycote 602EF is nonflammable, does not use any chlorofluorocarbons (CFC's) during product manufacture, and is in general, chemically inert. Braycote 602 is an excellent lubricant, has good shear stability, and low acute toxicity. Braycote 602EF is compatible with most commonly utilized materials, plastics and elastomers. It may be adversely affected by Lewis Acid catalysts such as aluminum chloride, at elevated temperatures. Newly exposed rubbing surfaces of aluminum, magnesium, or titanium alloys may react with Braycote 602EF under certain conditions. Such systems should be thoroughly evaluated. Surfaces must be well cleaned or 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. Special mention about the molybdenum disulfide in this product: Braycote 602EF is unique among the Braycote family of products because it contains a fine particle dispersion of MoS2. For example, would the MoS2 catalyze corrosion with certain metals, such as copper based alloys. We have never heard of any customers using this product to encounter problems that were specifically the result of the MoS2. We do believe that MoS2 is a very stable compound and not likely to react with a metal surface. However, some applications do involve elevated temperatures at the point of contact and those temperatures theoretically, could become high enough to degrade the MoS2 which then could lead to some type of chemical reaction. The other concern is that the MoS2 could be somewhat abrasive when used against soft metals, and the generated metal particles could themselves corrode. We don't know of any instances where this actually happened but we only want to point out this possibility. Extreme performance and what it means: This product, with the molybdenum disulfide, means that if the product is exposed to extreme temperatures, and far above the normal use temperature of the product, and the lubricant is destroyed, it is hoped that the remaining moly disulfide will serve as a dry lubricant for a short period of use. In general, the family of Braycote greases are not good moisture barriers or at inhibiting corrosion. Braycote 602EF does not contain a corrosion inhibitor, but Braycote 601EF does. So if corrosion of a concern, perhaps Braycote 601EF should be considered instead.

Braycote Castrol Micronic 803 High Vacuum Grease 10 Gram Syringe PN 05042-AB Castrol Micronic 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. Braycote Micronic 803 features excellent room temperature outgassing characteristics and high temperature stability (-63°C to +260°C) and is also acceptable for use in clean rooms. Coefficient of friction is 0.06 as measured by ASTM Method D2266. With a perfluorinated polyether grease, such as Braycote Micronic 803, O-rings need not be lubricated as frequently. 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 Castrol 601EF High Vacuum Grease 10 Gram Syringe PN 05086-BA Braycote 601 EF is a smooth, buttery, translucent, off-white, NLGI #2 grease. Its base oil is a perfluorinated polyether, with exceptional chemical resistance, extremely low volatility, and a wide temperature service range. The grease is non-toxic, nonflammable, and does not use any chlorofluorocarbons (CFC's) during product manufacture. This product exhibits unusually high load-carrying capabilities as measured by the Four-Ball EP Test, and contains a rust and corrosion inhibitor for extra component protection. Braycote® 601EF features excellent resistance to fuels and oxidizers. It has a useful temperature range of (-80°C/-112°F to +204°C/399°F) and also features good low torque capabilities. The Braycote® 601EF high performance vacuum grease has been reformulated for manufacturing under more environmentally friendly circumstances and therefore carries the EF next to the product designation. Virtually all users should find the new 601EF to be indistinguishable from the original Braycote 601. Compatibilities: The product is compatible with most plastics, metals and rubbers. Extensive information is available about chemical resistance to various chemical species for perfluoroether lubricants, but not specifically for Braycote 601EF. MIL-Spec Status: Braycote 601EF at the present time does not comply with any specific MIL-Spec. However, as is always the case when selecting a vacuum grease, you have to do your own testing to make certain that would be the correct situation in your specific case.
