DENSO®-Tec


Petrolatum tape for sealing and for corrosion prevention on metallic components, pipes and fittings at temperatures up to +50°C (+122°F).

  • For operating temperatures of -40°C (-40°F) to +35°C (+95°F).
  • For design temperatures of -40°C (-40°F) to +50°C (+122°F).
  • High plasticity and flexibility.
  • Electrically insulating and diffusion-resistant.
  • Easiest manual processing.
  • DENSO®-Tec is a petrolatum-based corrosion prevention tape that can be processed cold.
  • DENSO®-Tec consists of an impregnated polypropylene non-woven carrier, which is coated on both sides with a corrosion prevention petrolatum mastic. The petrolatum mastic is stabilised by polymer additives, which means that it can be used at operating temperatures of -40°C (-40°F) to +35°C (+95°F).
  • DENSO®-Tec is impermeable to water and highly resistant to hydrous electrolyte solution.

DENSO®-Tec : Industries and solutions

DENSO®-Tec is primarily used for corrosion prevention on metallic construction components that have complicated shapes, or uneven surfaces in pipelines and in power station and pipeline station construction. DENSO®-Tec has even proven its innovative characteristics in less common applications, including use as a galvanic isolation layer, to prevent corrosion on cooling pipes or heat-retaining insulation, or to prevent corrosion on metal parts or pipe systems encased in concrete or screed.
