MOLYKOTE-P-37 (500-Gram-Tin)

MOLYKOTE® P-37 Paste

Overview

MOLYKOTE® P-37 Paste is an extremely pure, high-temperature anti-seize and solid lubricant paste designed for bolted joints operating under severe thermal and mechanical loads. Formulated without intentionally added lead, nickel, sulfur, chlorine or fluorine, it provides exceptional load-carrying capability, seizure protection and reliable disassembly of threaded fasteners after prolonged exposure to elevated temperatures. Its low-seepage formulation makes it particularly suitable for clean, high-performance industrial and aerospace applications.
