Belzona 5841

Epoxy coating that requires minimal surface preparation, ideal for on-site repair and protection of hot metal surfaces prone to corrosion under insulation

A solvent-free, 2-part epoxy coating designed to provide outstanding protection to hot metal surfaces against corrosion under insulation (CUI). This surface-tolerant coating can be applied by brush directly onto hot metal surfaces from 30°C to 80°C (86°F – 176°F) with minimal preparation required.

Key benefits

  • In-situ application by brush on live equipment operating at high temperatures with minimal surface preparation
  • Excellent corrosion under insulation (CUI) protection of surfaces up to 80°C (176°F)
  • Reduced health and safety risks as it is solvent-free
  • Fast cure allowing equipment to be re-insulated with minimum delay
  • Good chemical resistance against a wide range of chemicals
  • Excellent adhesion even to manually prepared metals including stainless steel, carbon steel, aluminium, brass and copper
  • Good adhesion to Belzona 5851 (HA-Barrier)* coating in overlap areas

Applications for Belzona 5841 include:

  • Prevention of corrosion under insulation (CUI)
  • Long-term corrosion protection of hot pipework and process equipment
  • In-situ external coating of process vessels operating at high temperature during service, avoiding production downtime

*Also available is heat activated Belzona 5851 (HA-Barrier) coating, suitable for applications onto hot surfaces up to 150°C (302°F).
