Anti-friction composition is a mixture of polymeric binders and organic solvents filled with fluoroplastic-4D. This composition is used to insulate wires and cover metal products with an anti-friction coating that protects them against atmospheric corrosion.

A coating made of anti-friction composition combines valuable technical properties of fluoropolymers, such as high chemical, weather and tropical resistance, elasticity, heat and frost resistance, as well as good dielectric and anti-friction properties. It provides good adhesion to metals, fiberglass, a number of plastics, wood, rubber, glass and other materials.

Our FBF-74D anti-friction coatings can used as a solid lubricant:

  • in hard-to-get-at spots in equipment at a high specific pressure on the coating;

  • in dusty conditions when conventional lubricants are ineffective;

  • in equipment working in seawater.

Operating temperatures range from -60 °C to +125 °C or up to 250 °C for short periods of time.

The surface of the coating is smooth and after drying it should not have a reticulated or honeycomb structure which could be seen with the naked eye. It should not come off a metal surface or crumble either. There may be variation in colour.

Our anti-friction coatings are produced in accordance with technical standards (TU) and the state sanitary norms and regulations.

The standard procedure of coating surfaces with FBF-74D anti-friction composition consists of the following steps:

  • The item should be free of dirt and rust. It should be sandblasted or beadblasted, degreased with gasoline and then with acetone.

  • Composition can be applied by curtain coating, or by using a brush or sprayer.

  • If necessary, streaks can be diluted and rinsed with ethanol.

  • The item is then placed in a drying oven for 60 ± 5 minutes at +55 °C (± 5 °C).

  • If more layers of coating are needed, the item should be cooled to room temperature, after which the second and the following layers are applied as described above.

  • In order to consolidate the coating and give it the final physical and mechanical properties the item is heated at a temperature of +155 ± 5 °C for at least an hour, then cooled to room temperature.

  • The thickness of a single-layer coating is 10-30 µm, depending on the way of application. Composition consumption at a layer thickness of 100-120 µm is about 200 g/m2.
