High-purity anti-seize paste for bolt connections exposed to extreme heat. Provides excellent resistance up to +1400°C, prevents galling, ensures easy disassembly, and meets Siemens, GE, EDF, and Pratt & Whitney standards.
DuPont™ MOLYKOTE® P-37 Anti-Seize Paste is a heavy-duty, high-purity solid lubricant paste developed for bolt connections exposed to extreme temperatures. Its advanced formulation is free of lead, nickel, sulfur, chlorine, fluorine, and PTFE, ensuring safe use in critical applications such as turbines, nuclear systems, and aerospace engineering.
Operating reliably from -30°C to +1400°C, MOLYKOTE® P-37 delivers exceptional anti-seize protection, reducing friction (μ = 0.11) and supporting high load resistance (5,500 N welding load, 1.50 mm wear scar per DIN 51350). It prevents bolt seizure, supports smooth assembly and disassembly, and reduces maintenance time.
