Anti-friction CoatingsInvisible and effective
Anti-friction coatings are lubrication solutions that are dry to the touch, which have a similar formulation to industrial coatings.
The BECHEM Berucoat AF, Berucoat AK, and Berucoat FX product series impress with a number of benefits, outstanding quality characteristics, and offer individual applications for all areas of industry, especially for bulk goods and mass-produced parts, manufactured from various metallic materials, plastics, elastomers, and leather materials.
BECHEM anti-friction coatings can be applied to thoroughly degreased surfaces using standard application methods for industrial coatings, such as spraying, immersion, barrels, brushes, or dip centrifuging.
The Berucoat MC series uses the innovative BECHEM microcapsule technology for needs-based anti-friction coating dosing.
BECHEM non-friction coatings can be used in a range of applications. For instance, as anti-friction coating films in automated production and assembly or as support for the running-in of highly stressed machine elements. They are also suitable for use as an assembly aid or as maintenance-free lifetime lubrication. The multitude of possible applications often require customized solutions that we develop together with you in order to minimize wear as well as maintenance and service costs. BECHEM is a strong production partner, offering both expertise and product innovations.
Typical applications of non-friction coatings:
- Motor pistons
- Compressor pistons
- Cam shafts
- Gear boxes
- Locking systems/locking cylinders
- Telescopic cranes
- Spindles (small gear boxes, textile industry)
- Slide rails

- Improved assembly options for machine elements
- Minimizes the maintenance expense
CO2 reduction not only presents a huge challenge for the stability of the piston, but also for the anti-friction coating.
Choosing a suitable anti-friction coating begins with looking at the material to be coated and the material of the friction partner. BECHEM products are as unique in their design as the materials and material combinations themselves. Whether metal, plastic, elastomers, leather, or wood are rubbing against the same or a different material partner, we have the right solution for virtually all material combinations.
The surface treatment of materials to be coated is absolutely critical for the adhesion and service life of the anti-friction coating. Optimal adhesion can be achieved with surface pretreatment aligned to the anti-friction coating and the component. Depending on the requirement for the adhesion and service life of the anti-friction coating, the thorough removal of all residues, such as dust, dirt, or rust, as pretreatment may already suffice.
Galvanizing/nickel-plating as well as phosphatizing and sand blasting have become established methods of pretreating metallic materials. All procedures create a rough or porous surface that enables a mechanical bond with the anti-friction coating for significantly better adhesion.
During galvanizing/nickel-plating and phosphatizing, an additional corrosion protection is formed on metallic surfaces, which can be enhanced using tailored BECHEM anti-friction coatings.
Even for plastics, the roughening of the surface with acid treatment can lead to much better adhesion. As an alternative, various oxidative methods, such as plasma and corona treatment, create polar chemical groups on the material surface, which enable a firm bond with the anti-friction coatings.
BECHEM anti-friction coatings can be applied using standard application methods for industrial coatings, such as spraying, immersion, barrels, brushes, or dip centrifuging. The application procedure usually depends on the component geometry and the resulting attainable properties of the anti-friction coating. BECHEM offers custom consultation in selecting the most efficient application method that best fits the application.
This most common application technology can be used to coat virtually any component geometry, applying a uniform layer thickness.
If components weigh less than 5 g, the spray barrel method can be used. Spraying the parts in a rotating barrel prevents the coated components from sticking.
This method is an inexpensive alternative to spraying when certain that the components cannot stick due to their geometry. Components from 20 - 100 mm weighing up to max. 150 g can be coated in an immersion centrifuge.
