Functional coatings

Functional coatings are used when fastening elements require a coating that assume a technical function.

They consist of different polymer compositions, such as polyamide, plastisol, polyolefin, etc., and are used acc. to your demands.

Functional coatings are system solutions for mechanically stressed fastening elements, such as screws and nuts.

These coating types are applied using different application procedures. Depending on the coating, they can assume a locking, securing (captive) or holding, sealing function.

Advantages:

  • Integrated safety
  • Rational safety
  • High securing action
  • Prevents loss of screw
  • Captive part of the thread  

Please contact us directly for further information or quotation. We would be happy to support you with our experience to find the optimum solution for your specific application requirements.
