MOLYKOTE® M-77 Paste is a silicone-oil-based paste formulated with solid lubricants, including molybdenum disulfide. It offers both paste and dry lubrication and is commonly used to lubricate metals, plastics, and elastomers.
MOLYKOTE® M-77 is a high-performance lubricant paste formulated for applications with low to moderate speeds and extreme high temperatures. MOLYKOTE® M-77 is engineered with a high-quality polyphenylmethyl siloxane oil, a lithium soap thickener, and solid molybdenum disulfide (MoS2) particles for enhanced medium-load protection.
MOLYKOTE® M-77 is designed to volatilize at extreme temperatures, leaving behind a dry film lubricant layer of MoS2 for long-term surface protection.
