Molykote® coating: innovative solutions in gear industry

What is molykote® coating? Process and application

• Surface preparation: before applying molykote® coating, it is crucial to adequately prepare the gear surface. This may include phosphating, which improves coating adhesion. Alternatively, methods like sandblasting, shot peening, or micro-sandblasting can be used to prepare the surface.

• Coating application: molykote® coating can be applied in various ways, including immersion, spraying, or, in specific circumstances, with a brush. This layer of molybdenum disulphide is uniformly applied to the gear surface.

• Annealing: after application, the gear undergoes annealing in a circulating air oven. This polymerization process is essential to securely bond the lacquer to the gear surface.

Features and benefits

• Dry self-lubrication: one of the primary advantages of molykote® coating is its ability to help dry self-lubrication. This means that treated gears can operate without the need for additional oils, greases, or lubricants.
• Corrosion protection: this treatment forms a protective barrier on gear surfaces, preventing corrosion and oxidation. This is particularly crucial in aggressive or moisture-exposed environments.
• Reduction of friction coefficient: molykote® coating significantly reduces the friction coefficient between gear surfaces, enhancing efficiency and reducing wear.
• Improved anchoring: it can be applied to previously phosphated surfaces to enhance coating adhesion, thus increasing its longevity.
