Mechanical protective coating for the welding seam area on plastic pipes, especially suited to trenchless laying techniques.

  • Outstanding protection of welding seams on plastic pipes.
  • High mechanical stability and abrasion resistance.
  • Simple, safe application using two-component cartridges.
  • Rapid curing.
  • LIQUITOL®-HK7 is a rapidly curing, mechanically hard-wearing coating based on polyurethane. LIQUITOL®-HK7 is characterised by its high abrasion resistance and impact strength.
  • Thanks to these properties, LIQUITOL®-HK7 is an ideal protective encasement in the welding seam area on plastic pipes that have protective wrappings.
