PCP and EPDM

Rubber-Based Anti-Corrosion Systems

Shawcor offers two rubber-based custom coating systems: PCP (polychloroprene) coatings for operating temperatures up to 95°C and EPDM coatings for temperatures up to 130°C. Both systems can be applied onto straight lengths of pipe, field joints, bends, fabricated spools and other custom structures. PCP can also be internally applied to spools. PCP and EPDM are proven solutions for specialized applications such as splash zones, internal linings for riser clamps, and anti-fouling coating projects.

Proven Performance

  • Provide good anti-corrosion performance in specialised applications such as splash zones on risers
  • EPDM can also be used as a thermal barrier underneath thermal insulation coatings such as polyurethane-based systems

Customised Application Processes

  • PCP and EPDM coating systems can be applied as external coatings through extrusion and by hand wrapping
  • PCP (polychloroprene) can also be internally applied to spools, and can be used as a lining for riser clamps or as an external anti-fouling coating by the application of a 3 mm thick outer layer of PCP containing copper nickel granules (this system is called cupoprene)

Engineered Solutions

  • The PCP and EPDM systems allow for a wide range of technical performance designs based on the specific requirements of each project
  • Can be used for coating straight lengths of pipe, field joints and custom parts such as bends and fabricated spools
