Accurate edge offers Molybdenum disulfide coating that are Coatings (MoS2 coatings), also known as Moly Coatings are commonly used in applications where load carrying capacity, operating temperature and coefficient of friction are primary concerns. This coating provides effective lubrication in a wide range of loads, in many cases exceeding 250,000 psi. Moly coatings lubricate sacrificially by transferring lubricant between the two mating surfaces, which helps to reduce wear and coefficient of friction. Molybdenum disulfide (MoS2) coatings are a dry film lubricant.
Moly Coating Properties: Moly coating is a combination of molybdenum disulfide lubricant and high performance resins. Molybdenum coatings are thermally cured and thoroughly bonded to the base metal of the coated part. Uses for molybdenum disulfide coatings include applications that require a lubricant that is more unreactive when in use, and remains sturdy. We offer Molykote coatings, Everlube coatings, Lube-Lok coatings, Ecoalube coatings, Ever-Slik coatings, and more.
FAQ about Molybdenum Disulfide (MoS2)
Molybdenum Disulfide, often called “Moly” coating, is a dry film lubricant that excels where liquid oils and greases fail. Its unique molecular structure consists of layers that slide easily over one another, providing an extremely low coefficient of friction. In high-pressure environments – often exceeding 250,000 psi – the coating acts as a sacrificial barrier that prevents direct metal-to-metal contact. This is particularly critical for stainless steel fasteners and threaded components in the UAE’s oil and gas sector, where it prevents the permanent “cold welding” or galling that can occur during high-torque assembly.
While Graphite requires moisture to provide lubrication, Molybdenum Disulfide is a superior choice for vacuum or space-grade applications because its lubricating properties are inherent to its crystal structure and do not depend on water vapor. In terms of temperature, MoS2 remains stable from cryogenic levels up to 400°C (750°F) in normal atmospheres, and even higher in non-oxidizing environments. This makes it the standard for aerospace and subsea components in Dubai where equipment must endure extreme thermal shifts without the risk of lubricant evaporation or migration.
At Accurate Edge, our Molybdenum Disulfide coatings are applied to meet rigorous international and military specifications, including AS5272 (formerly MIL-L-46010) and ASTM 2625. These standards ensure the coating provides maximum wear life and load-carrying capacity. We typically apply the coating to a thickness of 0.0002 to 0.0005 inches, ensuring it does not interfere with the precision tolerances of gears, bearings, or valve internals while providing a salt spray resistance that protects against the corrosive maritime climate of the UAE.
