Application of RD-6® using the wrapster

Features & Benefits

RD-6® is a non-shielding coating.

  • If the coating ever becomes disbonded, the pipeline is still protected because cathodic protection currents can reach the disbonded area. Once there, the current will raise the pH of the water underneath the disbonded area to 9 or higher - a level too high to support corrosion.
  • The geotextile fabric backing of RD-6® does not shield cathodic protection currents. 

RD-6® is less likely to fail (to become disbonded) because:

  • RD-6® resists disbondment from the pipe, even if surface preparation is less than perfect. F
  • RD-6® is highly resistant to soil stress, a major cause of coating disbondment. 
  • RD-6® application time is quicker than almost any other coating, and requires no cure. 

RD-6® has a long record of successful installations in the field.

  • The first installations of RD-6® were in 1988. By 1992, the product was being widely used in North America. Today there are thousands of installations.
