Krytox 280AC Grease | Anti Corrosion & Rust Protection
Superior lubrication that contains 1% sodium nitrite
Krytox 280AC series anti-corrosion greases are white greases that contain sodium nitrite. These grades provide rust protection at ambient temperatures, corrosion protection at high temperatures, and anti-wear protection. Krytox greases are clear, colorless, fluorinated synthetic oils that are nonreactive, nonflammable, safe in chemical and oxygen service, and are long-lasting. Krytox is a perfluoropolyether (PFPE)—also called perfluoroalkylether (PFAE) or perfluoropolyalkylether (PFPAE).
Since the first commercial application over 50 years ago, Krytox synthetic lubricants have delivered consistent, superior, extended performance. Today, with new additives for new challenges, Krytox lubricants continue to deliver extreme performance under extreme conditions. Krytox 280 series is the lubricant of choice for demanding conditions —high and low temperatures, extreme pressure, and harsh environments.
Why Krytox 280AC?
All standard grades of grease are thickened with high-efficiency PTFE, whose formula is (CF2-CF2)n. This special high-efficiency thickener has a melting point of 325°C (617 °F), and has low molecular weight and submicron (0.2 μ) particle size for higher performance in bearings.
