Belzona 5841

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
