Krytox™ 283AD Grease is a corrosion inhibited grade of Krytox™ 240AD
Krytox™ 283AD series anticorrosion greases are white greases containing sodium nitrite.
End Markets: Aerospace & Aviation; Transportation
Krytox® 283AD is mainly used for aerospace applications with higher temperatures, requiring a heavier molecular weight highest viscosity base oil and rust and corrosion inhibitor additives.
Related Applications: Bearings; Control Cables; Noise, Vibration, Harshness; Plain Bearings, Bushing & Sleeves; Plastic Lubrication; Reactive Service; Rubber & Elastomer Lubrication; Slides, Guides, & Tracks; Valves, Packings, Seals & O-Rings
Krytox™ 283AD greases provide rust protection at ambient temperatures, corrosion protection at high temperatures, and antiwear protection.

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.
