Molykote® D-321R is formulated with molybdenum disulfide (MoS₂) for demanding metal interfaces. It excels in applications involving slow to medium-speed sliding, oscillating, or intermittent motion under high loads. The coating is air-drying and offers excellent resistance to aging and stick-slip effects, making it ideal for permanent lubrication of sliding guides, gear wheels, and adjustment mechanisms. It performs reliably in extreme environments including high vacuum, elevated temperatures, and cold extrusion processes. Proven uses include cylinder-head bolts, car mirror adjusters, toaster guides, high-voltage switches, and rotor components in wind energy systems.

• Air Drying - Molykote® D-321R cures through air drying, allowing easy application without the need for high-temperature baking. The coating dries completely in approximately 23 seconds at 23°C, forming a uniform lubricating layer with a nonvolatile content of 29%. Once cured, the film adheres strongly to metal substrates, achieving adhesion strength above 1.5 N/mm² under ASTM D3359 testing. 

  
  

• Stick-Slip Prevention - The MoS₂-based solid lubricant structure minimizes the stick-slip phenomenon, which commonly occurs in sliding or oscillating motion under varying loads. Testing on steel-to-steel contact shows a stable friction coefficient below 0.10, even when subjected to intermittent speed changes or high-frequency oscillations. 

  
  

• High Aging Resistance - Molykote® D-321R provides long-term thermal and oxidative stability. The cured film maintains its lubricating capability between -180°C and 450°C without significant degradation. This stability ensures reliable lubrication in extreme temperature environments where conventional greases would fail or evaporate.

• Automotive - Molykote® D-321R is used in mirror adjustment mechanisms, gear wheel run-in, and chassis components exposed to high loads and vibration. Testing under continuous motion cycles confirmed a 30% reduction in frictional torque and extended operational life in adjustment assemblies, providing quieter and more stable mechanical movement.

  
  

• Aerospace - In rotor head components and high-load sliding interfaces, the coating reduces friction and prevents wear under severe mechanical stress. Performance evaluation at 350°C under 1,000 N load demonstrated stable friction characteristics without seizure, making it suitable for aerospace linkages and joint systems exposed to extreme dynamic forces.

  
  

• Industrial Machinery - The product is applied to sliding guides, cold extrusion dies, and oscillating mechanisms operating under continuous stress. Friction and wear analysis revealed up to 40% lower surface wear compared to untreated components after 10,000 sliding cycles, ensuring precise movement and long-lasting tool protection.

  
  

• Electrical Equipment - Molykote® D-321R serves as a dry lubricant for high-voltage switches, circuit connectors, and moving contacts. It prevents metal galling and contact sticking, improving current stability. Long-term tests under high temperature and electrical load confirmed consistent conductivity and reduced maintenance requirements for switchgear components.

  
  

• Renewable Energy - The coating provides durable lubrication for wind turbine rotor interfaces and pitch control systems. It maintains stable film integrity under high torque and alternating loads, reducing frictional losses and extending service intervals. Field trials in offshore conditions showed excellent corrosion resistance and minimal film deterioration after 2,000 operating hours.

  
  

• Consumer Appliances - Molykote® D-321R is applied to toaster guides, sliding rails, and precision metal parts requiring clean and maintenance-free motion. In operational testing, it demonstrated a 50% reduction in frictional drag and complete elimination of mechanical sticking over 20,000 motion cycles, improving appliance durability and performance consistency.

  
  

• Metalworking - The coating is used for groove-free cold extrusion and threaded fasteners under stress. By forming a uniform MoS₂ layer, it reduces friction coefficient by up to 45% compared to uncoated metal, enabling smoother forming operations and higher output consistency. Its solid film structure also prevents tool seizure, lowering replacement frequency and production downtime.
