Carboline Polyclad 951 is a two-component, wo-component, epoxy lining for “dry” natural gas transmission pipelines. It is designed to increase flow efficiency of natural gas in pipelines. This lining provides a smooth surface inside the pipe that will increase flow and reduce energy cost of transporting natural gas. Polyclad 951 offers corrosion protection of pipes during storage. It fully meets criteria of API RP 5L2 for gas transmission pipelines.

  • This product simply requires the substrate temperature to be above the dew point
  • Condensation due to substrate temperatures below the dew point can cause flash rusting on prepared steel and interfere with proper adhesion to the substrate

Health and Safety

Clean Up

  • Use Thinner 2 or Acetone
  • In case of spillage, absorb and dispose of in accordance with local applicable regulations


  • Observe the precautionary notices on the container label, and read the safety data sheet before use
  • Employ normal workmanlike safety precautions


  • When used as a tank lining or in enclosed areas, thorough air circulation must be used during and after application until the coating is cured
  • The ventilation system should be capable of preventing the solvent vapor concentration from reaching the lower explosion limit for the solvents used
  • User should test and monitor exposure levels to insure all personnel are below guidelines. If not sure or if not able to monitor levels, use MSHA/NIOSH approved supplied air respirator


  • This product contains flammable solvents
  • Keep away from sparks and open flames
  • All electrical equipment and installations should be made and grounded in accordance with regulations
  • In areas where explosion hazards exist, workers should be required to use non-ferrous tools and wear conductive and non-sparking shoes
  • Refer to the product data sheet and safety data sheets in the attachments section above for further details
