Erosion-Corrosion Resistant Coating for Immersed Conditions.

Belzona 1381 - Erosion-Corrosion Resistant Coating for Immersed Conditions.


Belzona 1381 is a two-component coating designed to protect equipment from erosion and corrosion damage. Specifically, this system is suited to equipment operating under continuous immersion at temperatures up to 95°C (203°F).

This next-generation coating benefits from being spray-friendly. Combined with a 24-hour overcoat window, Belzona 1381 allows for large applications to be effectively and quickly completed, dramatically reducing downtime.

This solvent-free coating also offers outstanding chemical resistance and is available in light colours, aiding visibility during application and inspection in dark vessels.


Key Benefits:

  • High-temperature epoxy coating providing outstanding erosion and corrosion resistance under immersed conditions.
  • Rapid application by airless spray without wear to spray equipment; can also be brush applied where required.
  • Allows for one or two coat application with 24 hours overcoat window.
  • Capable of high-build application (> 1250 microns) in a single coat without sagging.
  • Excellent cathodic disbondment resistance.
  • Excellent flexibility, toughness and impact resistance.
  • Outstanding chemical resistance against a wide range of chemicals.
  • Available in light colours to aid visibility in dark vessels during application and inspection.
  • Application and cure at room temperature - no hot work involved.
  • Reduced health and safety risks as it is solvent-free.
  • Excellent adhesion to most metal surfaces including carbon steel, stainless steel and specialist steels.



Application Areas:


  • High temperature epoxy coating providing excellent erosion and corrosion resistance for process vessels, separators, pumps, heat exchangers and condensers operating under immersion.
  • Epoxy pipe lining for protection of girth welds on internal field joints.
  • Repair of worn and damaged chutes and hoppers.
  • Long-term corrosion protection of scrubber units.
