Chemours Krytox™ AUT 2245 PFPE Automotive Performance Lubricant
Categories:	Fluid; Lubricant; Perfluoropolyether (PFPE)
Material Notes:	AUT grades are formulated with unique additives to provide flexible options for anticorrosion protection for automotive equipment and heavy transportation parts, such as viscous fan clutch bearings, alternators, and idler bearings. 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. It is thickened with PTFE and contains sodium nitrite, a traditional anti-corrosion additive. All grease grades in the AUT series are based on Krytox™ AUT 1045 oil, an ISO 100-grade PFPE oil. Krytox™ AUT 1045 should be considered for any automotive application requiring the use of an oil, from bearings and small plastic gear boxes to NVH solutions. Information provided by Chemours Krytox
