Product Overview

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.

End Markets: Chemical & Petrochemical; Consumer Products; Oil & Gas; Transportation

Applications

Related Applications: Bearings; Electric Motors; Plain Bearings, Bushing & Sleeves; Pumps; Rubber & Elastomer Lubrication; Valves, Packings, Seals & O-Rings

Features & Benefits

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
