Molybdenum disulphide spray lubricant for mechanical parts subjected to high temperatures. The MOS2 additive binds firmly to friction metal surfaces forming a protective-lubricant film. Effective in a temperature interval from -150°C to + 250°C, up to 1000°C in inert atmosphere. It is not removed with water. It is chemically inert and maintains its lubricating characteristics unchanged for an exceptionally long time even in the most demanding conditions.
