Molykote® 7400 is a solid lubricant coating formulated with molybdenum disulfide and graphite in a water-based binder system. It cures to form a durable, low-friction film that protects metal surfaces under high mechanical loads and low-speed sliding conditions. The coating is ideal for applications where clean processing is essential, such as in gearboxes, bearing run-in, and press-fit assemblies. It offers excellent adhesion, wear resistance, and anti-seize properties, making it suitable for oscillating or intermittent motion. Its water-based formulation supports environmentally conscious manufacturing and reduces VOC exposure during application.

• Free from Flammable Solvents - Molykote® 7400 uses a water-based binder system without volatile or flammable organic solvents. This composition significantly reduces fire hazards and VOC emissions during production and application. Testing shows that its curing process at 20°C completes within 24 seconds, producing a nonvolatile content of 30% and ensuring stable adhesion. This makes the coating suitable for facilities that prioritize clean air compliance and safer working conditions.

  
  

• Water-Based Formulation - The product’s water-based design offers high application flexibility and excellent film uniformity. With a density of 1.16 g/ml at 20°C, the coating spreads evenly on metal surfaces, forming a consistent lubricating layer. The water medium allows easy dilution and cleanup while maintaining coating integrity. Unlike solvent-based coatings, it does not emit harmful fumes, contributing to improved environmental sustainability and operator safety.

  
  

• High Load-Carrying Capacity - The combination of MoS₂ and graphite solid lubricants provides excellent load-bearing performance. Friction and wear testing show that the coating maintains structural integrity under loads exceeding 1,200 N/mm² without visible surface scoring or film rupture. This ensures reliable operation of sliding metal interfaces under heavy stress, preventing adhesive wear and extending component lifespan.

  
  

• Low Coefficient of Friction - Molykote® 7400 achieves a low coefficient of friction, typically below 0.08 on steel-to-steel interfaces under dry conditions. Its solid lubricant layer minimizes start-up resistance and reduces wear during boundary lubrication. Comparative tests indicate a reduction in sliding torque by 35% compared to untreated metal surfaces, confirming its efficiency in low-speed, high-load environments.

  
  

• PFAS-Free Formulation - The coating is manufactured without PTFE or per- and polyfluoroalkyl substances (PFAS), aligning with modern environmental and safety standards. This eliminates concerns about long-term ecological persistence while maintaining superior lubrication and anti-wear performance. The absence of PFAS materials ensures regulatory compliance and positions Molykote® 7400 as a sustainable industrial coating solution.

• Automotive Industry - Molykote® 7400 is applied to sliding components such as seat adjusters, hinges, and clutch plates that experience high mechanical stress. Friction testing shows a 40% reduction in wear depth and a 30% decrease in noise output after 10,000 motion cycles. The coating maintains lubrication where oils or greases cannot be used, ensuring long-term reliability in vehicle interiors and mechanical linkages.

  
  

• Manufacturing Equipment - The coating is used on guide rails, cams, and mechanical couplings that operate continuously under high mechanical load. In durability tests, Molykote® 7400 retained 95% of its coating thickness after 100,000 motion cycles, preventing seizure and improving motion stability. It is particularly effective for components that require precise motion with minimal contamination risk.

  
  

• Metal Processing - Molykote® 7400 is ideal for forming, stamping, and press-fit operations. It reduces the coefficient of friction between metal surfaces by up to 50%, preventing galling and micro-welding. The film’s high adhesion ensures tool protection during repetitive metal-to-metal contact, lowering tool maintenance frequency and improving production consistency in high-volume manufacturing lines.

  
  

• General Industrial Lubrication - The coating serves as a dry lubricant for industrial mechanisms operating under cleanroom or dusty conditions where grease cannot be used. It provides stable lubrication between -40°C and 250°C, maintaining film integrity without softening or cracking. This enables reliable performance for equipment such as conveyor joints, actuators, and assembly systems that require consistent, long-term sliding performance.
