MOLYKOTE P-37 ultra-pure solid lubricant paste designed for bolted joints

Product Properties

                MOLYKOTE P-37 is an ultra-pure solid lubricant paste designed for bolted joints. Free from lead, nickel, sulfur, chlorine, or fluorine, complying with Siemens, GE, and other international standards.

Product Introduction

                   Formulated with mineral oil and specialized solid lubricants, P-37 delivers ​​extreme temperature resistance up to 1,400°C​​ and superior anti-seize performance. Low seepage (sulfur <250 ppm, halogens <200 ppm) ensures cleanliness compliance, enabling easy bolt removal after prolonged high-temperature exposure.

Enhanced Properties

• Extreme Performance​​: Solid lubricant remains non-brittle at 1,400°C; weld load reaches 5,500 N (DIN 51 350 T.4).
• Friction Control​​: μ=0.11 on M12 bolts; breakaway torque maintains 120.9 Nm (600℃/21h).
• ​​Longevity Proven​​: 102.4 Nm breakaway torque on Nimonic bolts after 4 weeks at 850°C.

Application Scenarios

• Designed for ​​gas/steam turbine bolts​​ (e.g., nickel-based alloys) in power plants.
• Field-proven in Siemens SGT-800 turbines to prevent bolt seizure above 1,000°C. Incompatible with other lubricants.
