MOLYKOTE U-N Paste
MOLYKOTE U-N Paste is a high-temperature solid lubricant paste for assembly, run-in, and permanent lubrication of components. MOLYKOTE U-N Paste is a specialized solid lubricant designed for high-temperature applications. Formulated with a synthetic carrier oil, it provides exceptional dry lubrication up to 450 C and can withstand temperatures as high as 630 C in restricted air environments. Its low coefficient of friction and high load-carrying capacity minimize friction and wear on lubricated components. Importantly, this paste is PTFE and PFAS-free.
Application involves cleaning contact surfaces and applying the paste evenly using a suitable tool (brush, cloth, etc.), removing any excess. For roller bearings, a specific application method is recommended involving cleaning with petroleum spirit and applying the paste between roller elements before assembly. At temperatures exceeding 200 C, the carrier oil volatilizes, leaving a residue-free, dry lubricating film. The paste is compatible with some natural rubbers and plastics, though testing is recommended before use in such applications.
