DENSO®-Cal


Cold-applied corrosion prevention tape for mechanically unstressed pipelines and pipeline components at operating temperatures up to +110°C (+230°F).

  • For operating temperatures of -40°C (-40°F) to +110°C (+230°F).
  • For design temperatures of -50°C (-58°F) to +120°C (+248°F).
  • High plasticity and flexibility.
  • Electrically insulating and diffusion-resistant.
  • No preheating of the surface required.
  • DENSO®-Cal is a corrosion prevention tape based on polymer-modified petrolatum, and can be processed cold.
  • DENSO®-Cal consists of an impregnated polyester fabric, which is coated on both sides with a corrosion prevention petrolatum mastic. The petrolatum mastic is stabilised by polymer additives and therefore permits temperatures of up to +110°C (+230°F).
  • DENSO®-Cal boasts an exceptionally high peel strength compared to other petrolatum tape products, even at increased temperatures.
