Krytox™ AUT 2245 Grease For Electric Motors in Automotive Applications. Contains traditional sodium nitrite anti-corrosion additive.
Krytox™ AUT 2245 Grease addresses a broad range of applications from O-ring to bearing lubrication over a wide temperature range where corrosion is a potential issue. Krytox™ AUT 2245 Grease is based on ISO 100-grade perfluoropolyether (PFPE) oil and a sodium nitrite anti-corrosion additive for automotive equipment and heavy transportation parts, such as viscous fan clutch bearings, alternators and idler bearings.
Unsurpassed oxidation resistance of base oil: - PFPE will not oxidize and gum up with age and use. Will not break down with high temperatures experienced in electric motors.
Operating temperature range from –44 to 200°C (–47 to 392°F)
Advanced PTFE thickener: - Special high efficiency thickener will not oxidize or break down with shear.
Lubed-for-life potential: - Typically, no need to re-lubricate bearings during lifetime of electric motor

Primary Chemistry: PFPE
Krytox™ greases are nontoxic lubricants that maintain their lubricity and viscosity properties to reduce maintenance costs associated with re-lubrication, component failure, and downtime in demanding applications. They are created by thickening synthetic perfluoropolyether-based oil (PFPE) with polytetrafluoroethylene (PTFE) powder.
