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.

BraycoteŽ 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 BraycoteŽ 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.
