Molykote® M-77 is a solid-lubricant paste formulated with silicone carrier oil to support metal-to-metal contact under extremely demanding conditions. It delivers a consistent dry-film lubricating effect that enhances user experience by reducing frictional noise, smoothing mechanical movement, and improving assembly feel. Even in applications involving high loads, low sliding speeds, or press-fit components, the paste offers stable, predictable operation, helping equipment maintain a cleaner, quieter, and more controlled performance profile.

• Wide Temp Range – Molykote® M-77 maintains reliable lubrication from approximately minus 45 to plus 230 degrees Celsius, so the paste does not melt or disintegrate during thermal cycling. This broad service window allows one product to cover cold starts and high-temperature running conditions in the same mechanism. It supports consistent torque and startup resistance across seasonal and process temperature changes, reducing the need for product changes in different climates.

  
  

• Oxidation Resistance – The silicone grease base resists oxidation when exposed to air and elevated temperatures, which slows down thickening and prevents the formation of hard residues. This controlled oxidation behavior extends relubrication intervals, especially in components that are difficult to access once installed. The stable chemistry helps keep sliding surfaces clean, contributing to predictable performance over long service life.

  
  

• Water Resistance – Molykote M77 Grease retains its lubricating properties in the presence of moisture, splash water, or short-term immersion. The paste structure adheres tightly to metal surfaces so that water flow does not easily wash it away. This water resistance is important for components exposed to condensation, outdoor humidity, or cleaning cycles, where loss of lubricant film would otherwise accelerate wear.

  
  

• Material Compatibility – The formulation is designed to work with many common engineering materials, including steel, cast iron, and various elastomer seals. The silicone carrier and solid lubricants are selected to minimize swelling or softening of sealing elements during long contact times. This compatibility reduces the risk of leakage and seal failure and makes the paste suitable for mixed assemblies with metals and polymer components.

  
  

• Low Volatility – With a density of about 1.95 grams per cubic centimetre and a penetration range of roughly 280 to 330 millimetres per ten strokes, Molykote® M-77 forms a dense, low-evaporation film. This helps maintain film thickness in enclosed or semi-enclosed systems and supports long-term dry-film lubrication without frequent top-ups.

• Automotive – Molykote® M-77 is widely used in automotive mechanisms that require dry-film or boundary lubrication, such as brake system components, door hinges, lock mechanisms, and seat adjustment rails. The paste reduces operating noise, improves smooth movement of sliding and rotating parts, and helps prevent fretting and corrosion in connections that experience vibration. 

  
  

• Industrial Machinery – In industrial equipment, the paste is applied to sliding guides, splines, threaded connections, and assembly joints that face high loads at relatively low speeds. The solid lubricants provide emergency running capability if the oil component is displaced, protecting surfaces during start-stop cycles and shock loading. This makes it suitable for presses, handling systems, and general mechanical drives where secure, long-lasting assembly lubrication is required.

  
  

• Maintenance and Repair – Molykote® M-77 is frequently chosen by maintenance teams as an assembly aid and long-term lubricant for repair work. It is used on bolts, pins, couplings, and press-fit parts to avoid galling during assembly and disassembly, simplifying future service operations.
