Bonded Coatings
Longer component service life thanks to optimal anti-friction properties
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.
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.
Advantages
- 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.
Bonded coatings protect metals against corrosion and wear.
These speciality lubricants ensure constant friction for the entire lifetime of, for example, safety belt components and 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
