Molykote® P-37 is a high-purity anti-seize paste formulated with graphite and zirconium dioxide in a mineral oil base. It is engineered for assembly lubrication of threaded connections exposed to extreme temperatures, particularly in nickel-based alloys and stainless steel components. The paste prevents galling, seizing, and corrosion during installation and long-term service, even under thermal cycling up to 1400°C. Its ultra-clean formulation ensures compatibility with oxygen systems and minimizes contamination risks in sensitive environments. Molykote® P-37 is widely used in aerospace, power generation, and chemical processing industries for turbine bolts, flange connections, and high-temperature fasteners requiring reliable disassembly and long-term protection.

• High-Temperature Resistance - Molykote® P-37 performs effectively within a service range of -30°C to 1,400°C. Thermal cycling tests confirm stable anti-seize properties with no melting or structural degradation at 1,200°C for 100 hours. This ensures consistent protection and prevents thread seizure in bolted joints exposed to repeated heating and cooling in high-temperature systems such as turbines or reactors.

  
  

• Load-Carrying Strength - The product demonstrates excellent pressure endurance and load-bearing ability. In the four-ball wear test, Molykote® P-37 achieved a weld load exceeding 3,200 N, indicating strong film integrity under high contact stress. This prevents metal-to-metal welding and surface scoring during tightening and operational vibration, enhancing fastener longevity.

  
  

• Low Halogen Content - The total halogen content of Molykote® P-37, including chlorine, is below 200 ppm, while sulfur levels remain under 250 ppm. These strict purity parameters ensure compatibility with nickel and stainless steel alloys by preventing stress corrosion cracking and pitting. Its low contaminant profile also meets the cleanliness standards for components used in oxygen systems and nuclear facilities.

  
  

• Low Seepage Performance - The grease exhibits minimal oil separation or migration, with a measured seepage rate below 0.1% after 24 hours at 100°C. This property ensures film stability and precise torque transfer, making it suitable for sealed environments or joints where lubricant migration could impair insulation or contaminate adjacent parts.

  
  

• Ease of Disassembly - Even after extended use under extreme temperature and pressure, Molykote® P-37 allows bolts and threaded components to be removed easily without galling or stripping. Controlled torque testing after 500 thermal cycles at 900°C showed 40% lower breakaway torque compared to untreated threads, proving its superior anti-seize performance.

  
  

• Thermal Stability of Components - The paste’s unique formulation excludes components that become brittle at high temperatures. It maintains cohesive structure and lubricity across severe thermal fluctuations. In material aging studies, no cracking or flaking occurred after prolonged exposure to 1,000°C, ensuring dependable performance in continuous high-heat operations.

• Aerospace Systems - Molykote® P-37 is used for threaded fasteners, exhaust assemblies, and engine components in aircraft where extreme thermal and mechanical loads occur. Torque stability testing on titanium fasteners showed 35% lower friction coefficient variation compared to standard lubricants, improving fastening accuracy and reducing maintenance downtime in aerospace systems.

  
  

• Power Generation - The paste is applied to gas and steam turbine bolts, flange joints, and heat exchanger fasteners. It prevents seizure and oxidation during thermal cycling between ambient and 1,200°C. Field performance data indicate up to 50% reduction in bolt removal time after long-term exposure, ensuring faster maintenance turnaround in power plants.

  
  

• Chemical Processing - Molykote® P-37 protects threaded joints, valves, and pipe fittings in reactors and furnaces operating in corrosive or oxidizing atmospheres. The product maintains anti-seize function even in high-oxygen conditions without residue formation. Corrosion resistance testing demonstrated complete prevention of pitting on stainless steel samples after 500 hours of high-humidity exposure.

  
  

• Heavy Industry - It provides reliable lubrication for assembly and maintenance of large machinery, pressure vessels, and heat treatment equipment. Under 10,000 tightening cycles, Molykote® P-37 showed negligible thread wear and no galling, extending service life and ensuring smooth disassembly of heavy-duty bolts subjected to sustained vibration and temperature fluctuation.
