Dry Film Lubrication

Our dry film lubricants provide friction control and surface release solutions for applications where liquid lubricants are impractical or could fail due to load or temperature. Reducing wear, galling, and heat generation on your components will reduce running and maintenance costs, machine downtime and operational limitations.
Our dry film lubrication service is delivered by an experienced, skilled workforce and supported by a comprehensive quality process that is able, depending on the individual specification, to carry out cure tests such as the MEK rub test, adhesion tests (such as ASTM D3359), or thickness tests to SSPC-PA2.

Molybdenum Disulfide (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.

Moly Coating Applications
Moly coatings have traditionally been applied on components subjected to high-pressures, whilst graphite coatings have been used in applications at high temperatures. Pre-treatment of the substrate, such as blasting to SA2.5, can have a marked effect on the end anti-friction quality of the component.

Dry-film lubricants like moly coatings are extremely useful for working parts which operate in an environment unsuitable for wet lubricants, or are positioned in awkward places that make wet lubrication very difficult. Different Molybdenum Disulphide coatings have variable degrees of corrosion and wear resistance qualities. The coating is suitable for heavily loaded mechanical applications, but not safe for food contact applications.
There are a number of application methods of MoS2 low friction coatings, including a simple rubbing or burnishing, air-spraying resin-bonded or inorganically bonded coatings, and more recently by sputtering through physical vapour deposition (PVD).
