Printing

Offset printing is a widely used technique for long print runs such as newspapers and magazines. A plastic coating is applied to a number of rollers inside the printing press in order to transport the ink or spread it over the rubberized roller. A special type of Rilsan® has been developed that we apply to both new and existing / renewed rollers.

For used rollers, the old Rilsan® layer is thermally removed in our pyrolysis furnace. We then sandblast the core and cover it with an oversized Rilsan® layer. This layer can be finished very precisely with any desired profile to make the roller enjoy it’s second life.

Frequently asked questions

An elastic coating is a plastic coating that does not harden after being applied and is called a thermoplastic. These plastics become soft again when they are heated to their melting point, even after many years.

The main elastic plastic coatings applied by Kersten are:

  • Rilsan®
  • Halar®
  • ETFE
  • Fluoropolymers
  • Abcite®.

These elastic coatings can be applied to metal surfaces that deform, such as springs. These coatings are also applied in case high wear is expected. As well, a thermoplastic coating is more resistant to cavitation than a thermoset.

Some examples of metals that can be provided with a plastic coating:

  • Carbon steel
  • Stainless steel
  • Aluminium
  • Brass
  • Titan
  • Cast iron

Our coatings are applied using thermal processes. For the application of the various coatings it is necessary to heat the metals. This can be done before or after applying the coatings.

Corrosion is damage to a (metal) surface due to various influences. The rusting of steel is the best known type of corrosion. However other metals, such as stainless steel, can also corrode.
