Molykote® P-40 is a metal-free assembly and lubrication paste designed for reliable performance under demanding mechanical conditions. It delivers a consistent, adhesive lubrication film that enhances smooth assembly, prevents fretting, and supports stable operation in environments exposed to moisture, vibration, intermittent movement, or corrosive factors. 

• High Adhesion – Molykote® P-40 forms a strong, persistent lubricating film on metal surfaces due to its optimized silicone-based binder and solid lubricant package. Adhesion performance is validated by standardized adhesion tests, showing stable film retention even after repeated mechanical movement. This strong adherence prevents displacement under vibration or load, ensuring consistent lubrication for assembled components.

  
  

• Corrosion Protection – The paste delivers measurable corrosion resistance supported by salt-spray performance data, where treated metal specimens demonstrate significantly reduced oxidation. Its active inhibitor system protects surfaces exposed to humidity, cleaning agents, or outdoor environmental cycles. This reduces maintenance needs and supports long-term reliability for metallic joints or press-fit assemblies.

  
  

• Water Resistance – Molykote® P-40 maintains its lubricating properties under splash water, condensation, or intermittent wet conditions. Testing shows that the paste retains structure and does not emulsify or wash off during water-spray cycles, ensuring stable lubrication. This water-resistant behavior makes it suitable for equipment operating in humid industrial settings.

  
  

• Fretting Resistance – The solid lubricant system reduces micro-movement wear, validated by fretting-corrosion test methods that show reduced material transfer and lower surface degradation. This provides protection in joints subjected to vibration, oscillation, or cyclic loading. Reduced fretting minimizes noise, performance decay, and premature component failure.

  
  

• Metal-Free Formula – Molykote® P-40 contains no intentionally added metals such as lead, nickel, copper, or zinc. This improves compatibility with sensitive assembly materials and reduces the risk of galvanic reactions. The metal-free formulation meets modern regulatory and environmental expectations while delivering stable mechanical protection across varied operating conditions.

• Automotive – Molykote® P-40 is widely used in automotive assembly lines for press-fit parts, threaded joints, sliding metal interfaces, and components subjected to vibration. Its strong adhesion and anti-fretting performance support reliable long-term operation in body assemblies, chassis connections, and mechanical modules.

  
  

• Heavy Machinery – The paste is applied to joints, bolts, and mechanical interfaces in construction and agricultural machinery. Its strong water resistance and corrosion-protection behavior help maintain stability in outdoor or dust-prone environments, reducing downtime caused by seized or worn components.

  
  

• Marine – Molykote® P-40 is suitable for shipboard mechanisms and equipment exposed to saltwater spray and high humidity. Its metal-free formulation and corrosion-resistant characteristics support dependable performance on vessels, docks, and marine motion systems.

  
  

• Industrial Equipment – Factories use Molykote® P-40 for assembly and preventive maintenance of presses, conveyors, packaging systems, and high-precision machinery. The paste reduces wear during intermittent movement cycles and supports stable lubrication in environments with moisture or chemical exposure.

  
  

• Rail & Transport – The product is used in couplings, brackets, joint assemblies, and mechanisms operating under vibration in rail and mass-transport systems. Its fretting-resistant and water-durable lubrication decreases noise, wear, and service interruptions during continuous transport operations.
