MOLYKOTE® P-37 High Temperature Anti-Seize Paste – Ultra-Pure Solid Lubricant for Bolted Joints 500g

MOLYKOTE® P-37 Paste is a high-purity solid lubricant paste developed for lubrication and anti-seize protection of threaded fasteners and bolted joints operating under extreme temperatures and heavy loads. The paste contains mineral oil combined with special solid lubricants that provide excellent load-carrying capacity and reliable seizure protection for critical fastening applications.
This high-temperature anti-seize paste is designed for environments requiring extremely pure lubricants. The formulation contains no intentional lead, nickel, sulfur, chlorine, or fluorine, making it suitable for applications where contamination control and cleanliness are critical. Its low seepage characteristics allow use in equipment where lubricant leakage must be minimized.
MOLYKOTE P-37 Paste maintains lubrication performance at extremely high temperatures, providing reliable friction control and protection for threaded components exposed to severe thermal stress. The paste prevents galling, seizure, and thread damage while ensuring that bolts and fasteners can be easily removed after prolonged exposure to heat.
The product is commonly used for screws, nuts, and bolts installed in industrial equipment operating at very high temperatures. Typical industries include power generation, turbine assemblies, high-temperature processing equipment, and heavy industrial machinery where reliable anti-seize protection is essential.
MOLYKOTE P-37 Paste is widely used by maintenance engineers and equipment manufacturers requiring ultra-high-temperature fastener lubrication and long-term anti-seize performance in demanding industrial environments.
