DuPont MOLYKOTE Lubricants for Aerospace Maintenance and GSA Procurement
Greases are the substance that keeps your fleet moving smoothly. It might seem like a slight overstatement, but it isn’t. Grease is the quiet substance that allows landing gear to swing as it should, flaps and slats to travel up and down, and a whole lot more.
DuPont has long been a leading name in DuPont MOLYKOTE lubricants for aerospace and government maintenance applications, with MOLYKOTE serving the aviation and aerospace industry for more than 75 years. Greenwood Aerospace is proud to support aircraft maintenance teams with specially formulated MOLYKOTE greases, solid lubricants, and dry film solutions engineered for demanding conditions.

Why MOLYKOTE Lubricants Are Trusted for Aircraft Maintenance
DuPont’s MOLYKOTE line of greases is purpose-built to sustain and support aircraft maintenance, overhauls, and numerous aerospace applications. Where reliability, safety, and performance are critical, accept no seconds.
MOLYKOTE lubricants are designed to operate in harsh environments across broad temperature ranges and under the extreme conditions that break down lesser lubricants.
What are MOLYKOTE Lubricants Used For in Aircraft Maintenance?
There are many types of grease used in aircraft structures, with different types and performance standards applied to different areas.

Greases in Aerospace: Function and Performance Requirements
Greases are widely used to lubricate metal-to-metal and metal-to-plastic contact points in aircraft systems.
Grease protects:
- Bearings
- Control cables
- Rollers and linkages
- O-rings, valves, and moving assemblies
There are a few common performance factors, such as base oil viscosity, temperature conditions, corrosion resistance, and friction resistance.
MOLYKOTE 33 Low Temperature Grease: Designed for Extreme Cold and High Reliability
MOLYKOTE 33 is a silicone-based grease engineered for light-load applications at high speeds and low temperatures. It is specifically designed for a wide temperature range and good oxidation resistance in critical components, and made for metal-to-metal and metal-to-plastic friction points where consistent torque and smooth movement are mandatory.
One of the key features of MOLYKOTE 33 is its wide temperature range -73 °C to 180 °C. It performs well in extreme cold and hot conditions. The grease has super-low-temperature characteristics, including low breakaway torque at sub-zero temperatures, which prevents binding, sluggish response, or inconsistent movement after cold soak.
The formulation has good oxidation resistance, which helps to maintain performance over long service life and reduces the risk of grease degradation in long-term installations. MOLYKOTE 33 is compatible with most plastics and elastomers, making it suitable for mixed-material assemblies in aircraft systems, and its water-resistant properties enable use in wet environments.
What Is a Dry Film Lubricant and Why Is It Used in Aerospace
Dry film lubricants cure to form a bonded, low-friction coating on a surface rather than remaining wet, as oils and greases do. Once cured, the lubricating layer operates without free-flowing lubes (oils and greases), eliminating migration, dripping, and contamination of adjacent components.
What Is MOLYKOTE D-321 R Used For?
MOLYKOTE D-321R is an air-curing, dry-film anti-friction coating designed for metal-to-metal contact under high loads and slow to medium sliding speeds. Unlike liquid lubricants, it forms a permanently bonded lubricating film that consistently reduces friction without oil or grease migration. It also does not accumulate dirt and grime like grease does, which is a major bonus.
MOLYKOTE D-321 R is for permanent lubrication of highly stressed sliding guides, components with oscillating or intermittent movement, and applications that require reliable performance under high vacuum and extreme temperature conditions. The coating is also used to improve the running-in process for heavily loaded parts and to reduce initial wear during the early service life.
What is MOLYKOTE Z Powder Used For?
MOLYKOTE Z-Powder is a solid lubricant made from molybdenum disulfide (MoS₂) for lubrication in tough and demanding situations where liquids and greases won’t work. Unlike dry film coatings that rely on binders, MOLYKOTE Z-Powder is a free-flowing solid, so it’s good in applications where oils, greases, or solvent-based coatings will degrade, evaporate, or attract contamination. This is one of the biggest problems with oils and grease: given their tacky, absorbent composition, they attract and retain dirt and grime very badly.
Z-powder is applied as a dry lubricating film on metal surfaces or used as a solid lubricant additive in self-lubricating plastics, sintered metal components, and metalworking compounds. It is also commonly specified for high-load, low-speed applications, press fit assemblies, and processes where high pressure and controlled friction are required for break-in and initial operations.
What Is MOLYKOTE M-77 Used For?
MOLYKOTE M-77 Paste is a solid lubricant paste with molybdenum disulfide (MoS₂) in a silicone carrier oil for low-speed and low-to-moderate-load applications. The formulation is for components exposed to water, heat, and extreme temperature cycling, where mineral oil-based lubricants may not perform M-77.
MOLYKOTE M-77 provides paste lubrication up to +230°C (446°F). Above this temperature, the silicone carrier oil evaporates, leaving behind a dry solid lubricating film that continues to lubricate up to +400°C (662°F). This transition from paste to dry lubrication enables M-77 to protect components across a wide temperature range without the risk of residue buildup or lubricant failure.
