Overview
Krytox™ 280AC Grease is a premier, specialty aerospace grease formulated to withstand the harshest conditions where conventional lubricants would fail. Krytox™ 280AC Grease is entirely nonflammable and chemically inert due to its formulation of perfluoropolyether (PFPE) oil and a polytetrafluoroethylene (PTFE) thickener system.
Krytox™ 280AC Grease is Krytox™ 240AC Grease with the addition of performance additives, including anticorrosion and rust-preventative inhibitors for enhanced surface protection. Krytox™ 280AC is an NLGI Grade 2 grease that provides exceptionally long-lasting performance for applications requiring added corrosion protection.
