An introduction to low friction coating

Low friction coatings provide dry film lubrication where liquid lubricants could fail or are simply impractical. Suitable for a variety of substrates including most metals, plastic and ceramic they provide low coefficient of friction to mating surfaces reducing wear, galling, and heat generation on components that can cause increased running and maintenance costs, machine downtime and operational limitations.

When applied as a thin, dry surface coating, PTFE and other low friction coatings provides the optimum balance of low friction, hardness and durability. Performance can also be enhanced by the addition of fillers to the formulation.

Thermally cured and bonded to the base material, low friction coatings provide a cleaner and more efficient solutions than grease, oils and traditional lubricants, although, they can also be used to provide secondary lubrication in the event of failure of conventional lubricants if required. 

Low friction coatings are suitable for tight tolerance parts with a coating thickness of only 10-20 microns.  

Dry film low friction coatings are durable and long lasting, offering many advantages over traditional lubricants.

Key features are:

• Outstanding lubrication
• High load carrying capacity
• Corrosion resistance
• Low Friction
• Non-stick
• Cryogenically Stable
• Chemical Resistance
• Hydrophobic
• High wear resistance
• Good resistance to oil, grease and solvents
• Wide temperature operating range: from (-250° to 285°C)

Typical applications include:

• Piston rings and tappets
• Saw blades
• Engine internals including pistons & transmission housing
• Bearings and hydraulic parts
• Rubber O rings
• Dog combs
• Chutes
• Locking components, sliding and oscillating parts
• Sub-sea hardware
• Fasteners and threaded components
• Ball valves
• Sliding and rotating systems
• Wind turbines
• Oilfield connectors and coupling
