C K Dry Moly is a dry-film lubricant use in situations with drastic pressure and temperatures (-28ºF to 600ºF). It packs micro-sized molybdenum disulfide that protects metal surfaces from rusting and corrosion. Any surface treated with C K Dry Moly will withstand water, oil, alkali, and most acids. It also reduces metal-to-metal contact on highly-machined surfaces. Its a convenient, long-lasting aerosol that sprays a thin, black coating that adheres and dries within seconds.
