Krytox™ 283AD Grease
Krytox™ 283AD Grease is an NLGI Grade 2, nonflammable, aerospace-grade PFPE lubricant with a PTFE thickener and rust-inhibitor performance additives for complex and critical equipment. Its base oil viscosity is 502 cSt at 38°C.
Krytox™ 283AD is a premium PFPE grease for aerospace, aviation, and defense applications where anticorrosion performance is required. Krytox™ 283AD is a heavy viscosity base oil with additional sodium nitrite for corrosion protection and anti-wear performance.
Krytox™ 283AD is a reliable, multipurpose aerospace grease for applications where failure is unacceptable across extreme temperatures. This performance aviation grease provides greater rust protection and nonevaporative performance compared to hydrocarbon-base lubricant solutions.
Specifications
Oil viscosity @ 20°C (68°F): 1,540 cSt Base oil: Synthetic PFPE Food-grade compatible (H1): No Meets MIL-PRF-27617: Yes Estimated useful range: −34°C to 288°C (−20°F to 550°F) Grease density @ 25°C (77°F): : 1.93 g/mL Oil pour point: −30°C (−20°F) Lubricant performance additives: Sodium nitrite (rust inhibition)
Primary Chemistry: Perfluoropolyether (PFPE)
Features & Benefits
Nonflammable Nonreactive/Inert chemistry Long-lasting performance Excellent thermal stability Easy application and nonmigrating Enhanced anticorrosion and anti-wear performance
Problems Solved
Unsafe, smoking, or flammable grease chemistries Aero grade bearing or component damage from inferior grease Substandard corrosion and wear prevention from lubricants
Applications
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.
Krytox™ Specialty Aerospace Performance Lubricants are PFPE based oils & greases that meet or exceed the strict requirements of the Aerospace, Aviation & National Defense industries.
