Overview
MOLYKOTE® U Paste is a versatile, high-performance solid lubricant paste formulated with a synthetic polyalkylene glycol (PAG) base oil, a lithium soap thickener, and solid molybdenum disulfide particles for enhanced surface protection. MOLYKOTE® U Paste exhibits excellent load-carrying capability and is stable in both low and high temperature environments (−40°F to 400°F).
MOLYKOTE® U Paste is formulated to completely volatilize the PAG oil at high temperatures, leaving behind a solid lubricant film of molybdenum disulfide (MoS2) for extended-term protection in difficult-to-reach places. MOLYKOTE® U Paste is suitable for use on plastic, metal, and laminated components. It is compatible with a broad range of elastomers and synthetic rubbers.
