Bonded coatings, also known as anti-friction coatings, offer many advantages compared to conventional oils and greases for high temperatures, applications with special hygiene requirements or highly loaded industrial machine elements. Our special tribo-coatings help you optimise the friction coefficients and sliding properties of your components and ensure longer lifetimes.

At a glance: bonded coatings from Klüber Lubrication

  • Longer service life: our special low friction coatings optimise friction coefficients and the sliding properties of components and reduce maintenance costs
  • High hygiene and safety requirements: while lubricants may drip from the friction point, bonded coatings form a solid and clean layer.
  • High thermal stability: bonded coatings can be used at temperatures exceeding 300 °C.
  • High-performance solutions: competence and expertise gained from more than 90 years of research and industrial experience

What are bonded coatings?

Bonded coatings, or anti-friction tribo-coatings, form a uniform, dry and low-friction lubricant layer on various materials and components.

A bonded coating has a composition similar to that of a coloured paint. However, instead of the coloured pigments it contains one or several solid lubricants.  The main constituents of a low-friction bonded coating are:

  • Solid lubricants: polytetrafluoroethylene (PTFE), molybdenum disulfide (MoS2), boron nitride, graphite or a combination of different solid lubricants
  • Binder: organic or inorganic, consists of 1 or 2 components
  • Solvent: organic or water

Good adhesion due to dry lubrication

Dry lubrication is always a good choice for industrial applications requiring a clean, for-life lubricant. Bonded coatings can also be used for both particularly low and high temperatures exceeding 300 °C.

Contrary to other lubricants, a bonded coating or anti-friction coating offers the advantage of forming a uniform adhesive layer on the component. The clean lubrication layer, which cannot be washed off and does not have to be renewed (i.e. lifetime lubrication), optimises your production conditions and helps reduce your maintenance costs efficiently.

The advantages of bonded coatings:

  • Completely cover components and form a uniform lubricant layer
  • No contamination due to dry lubrication
  • Reduction of friction and constant friction coefficients
  • Prevention or reduction of noise (no stick-slip)
  • Suitable for particularly high and low temperatures
  • Reliable lifetime lubrication

The right bonded coating for your specific requirements

Our product range includes bonded coatings for metal surfaces and plastics and elastomers.

Bonded coatings protect metals against corrosion and wear. They are particularly suitable for:

  • Applications subject to extremely high or low temperatures
  • Parts in contact with aggressive media
  • When exposed to UV radiation or X-rays
  • For use in a vacuum

These speciality lubricants ensure constant friction for the entire lifetime of, for example, safety belt components.

It is important to select the right bonded coating to ensure good adhesion to your components. Our product range comprises a wide selection of special bonded coatings for plastics like PA, PPS, ABS, PC, POM and PE.

Bonded coatings for plastics should:

  • Ensure low friction coefficients
  • Protect reliably against wear
  • Reduce noise (no stick-slip effect)
  • Extend the life of components

Good adhesion and compatibility with the elastomer material is an important selection criterion for bonded coatings. Moreover, the dry lubrication has to be:

  • Resistant to UV radiation
  • Resistant to elongation of up to 150 percent

Our special bonded coatings for seals (e.g. O-rings) and elastomers increase wear resistance and extend the lifetime of these materials. They also improve the optical and tactile characteristics of visible components, reduce noise, and facilitate assembly.
