Molybdenum Disulfide (MoS2) Aerosol Spray
MoS2 Aerosol Spray / Moly Spray / MoS2 Coating Spray
Molybdenum Disulfide (MoS2) Dry Lubricant Spray, also known as moly spray or MoS2 aerosol spray, is an aerosol-applied dry lubricant coating used where wet-film lubricants cannot be used. It bonds well with compatible substrates and forms a dry lubricating coating film.
Lowerfriction MK-MoS2-SP is designed for dry-lubricity applications across automotive parts, bearings, chain drives, cams, power-transmission components, precision gears, molds, dies, marine parts, robotics, actuators and industrial tooling. The product brochure lists a wide temperature range of -50°C to +450°C and high load-bearing properties. For application-specific support, contact Lowerfriction with your substrate, load, speed, temperature, expected quantity and shipping requirements.
Engineer / Procurement Summary: MK-MoS2-SP is a molybdenum disulfide dry lubricant aerosol spray supplied in 13 oz / 369 gram cans. It is intended for dry-lubricity applications where wet-film lubricants cannot be used. The brochure lists substrate bonding, coating-film formation, high load-bearing properties and a -50°C to +450°C operating direction. The SDS classifies it as an extremely flammable aerosol with serious eye irritation and narcotic-effects hazards, so the latest SDS should be reviewed before handling, storage, spraying or transport.
