Chemours Krytox™ AUT2E45 PFPE Grease for Electric Motors
Categories:	Fluid; Lubricant; Perfluoropolyether (PFPE)
Material Notes:	Krytox™ greases offer the potential for lubed-for-life properties in demanding electrical motor service. Krytox™ greases are non-oxidizing, water-resistant, nonflammable, and chemically inert. Krytox™ greases contain perfluoropolyether (PFPE) oil and a polytetrafluoroethylene (PTFE) thickener. The PFPE oil and PTFE thickener will not oxidize and gum up like ordinary synthetic or hydrocarbon-based greases. Krytox™ greases are recommended by many major bearing manufacturers for long-life lubrication in severe applications. The superior film-forming capability of Krytox™ greases provide a thicker oil layer and reduce wear. Krytox™ greases are compatible with metals and most seal materials, but require removal of all old lubricants from the motor bearings before application. Proprietary anti-corrosion additive.
