Product details

  • Type Pipe Repair Wraps
  • Vendor CS-NRI
  • Barcode CSNRI_PPR-220-1QT

The CS-NRI  PPR-220 is a solvent free, chemically resistant, two-part bulk epoxy primer used atop filler compounds, but underneath the repair wraps or tapes., It is used to optimize the bond strength with the pipe and the repair wraps. 


  • High-build capability without slumping or sagging
  • Can be over-coated as soon as it is dry to the touch
  • Resistant to a wide variety of inorganic acids, alkalis, salts and organic media
  • Machinable once cured


  • Any metal surface or surface with the epoxy fillers added.
  • Used in conjunction with patches, plugs and other leak repair techniques
  • Used to transition aggressive changes in geometry or large defects prior to installing ECR Systems

Store indoors in cool, dry, ventilated storage at temperatures below 35°C (95°F ) in original, unopened containers. Minimum storage temperature 15.5°C (60°F)


  • Epoxy application temperature: minimum of 5°C (40°F) or less than 3°C (37°F) above dew point
  • Base component should be warmed to 15.5°C to 25°C (60 to 77°F) before mixing
  • Over-coating time should not exceed 3 hours
  • Suitable for long-term immersion at temperatures up to 70°C (158°F) and intermittent contactwith pressurized steam up to 120°C (248°F)
  • Resistant to dry heat in excess of 200°C (392°F) dependent on load
