Belzona 5871
Belzona 5871 is a two-component, polymeric, 100% solids system providing a thermal insulation barrier with corrosion protection and thermal and sub- zero “cool-to-touch” properties.
This material is designed to be applied to metal pipework, ducting and other industrial equipment. Belzona 5871 is thermally insulating, providing protection against contact-burn injuries, eliminates corrosion/CUI, condensation and anti-icing, improving safety and durability.
Belzona 5871 can be applied by brush, cartridge or plural spray, expanding upon application to produce a lightweight, closed-cell foam. This reduces the surface temperature of metallic substrates to below 60°C (140°F) whilst providing corrosion protection.
Key benefits
- Excellent corrosion resistance prevents corrosion and eliminates corrosion under insulation (CUI)
- Belzona 5871 can be brush or spray-applied, for both small, complex geometries or rapid application over a large area
- Thermal and sub-zero cool-to-touch properties provide worksite personal protection and safety against contact-burn injuries
- Expands up to three times the thickness it was originally applied, reducing the numbers of layers needed compared to conventional coating systems
- Thermal insulation reduces the amount of heat transfer through a surface, increasing the efficiency of equipment
- 100% solids system

Belzona 5871 expands up to three times to produce a closed-cell foam, providing corrosion protection combined with thermal and subzero “cool-to-touch” insulation properties.
Applications for Belzona 5871 include:
- Pipework
- Ducting
- Tank/Vessel Externals
- Industrial machinery and equipment
HIGH-TEMPERATURE TANK COATING
Thermal Insulation with Corrosion and UV protection for refinery batch tank.
