Description
A two-component epoxy-based system applied by brush or spray for protection of metallic and non-metallic surfaces operating under immersion conditions in contact with water and aqueous solutions when potable water approval is required.
Use Belzona 5812DW in combination with Belzona 9241 aggregate to create a drinking water approved concrete rebuilding system for heavily damaged vertical and horizontal surfaces.
Key benefits:
- Effective protection of equipment operating under immersion conditions from corrosion damage
- Belzona 5812 DW is approved by NSF for the applications in contact with drinking water
- Reduced health and safety risks as it is solvent-free
- Easy application by brush or spray and cure at room temperature – no hot work involved
- Eliminates the need for replacement and reduces downtime
- Excellent adhesion to virtually any surface including cast iron, stainless steel, brass, copper, concrete, wood, fiberglass and aluminium
Applications for Belzona 5812 DW:
- Metal and concrete structures in contact with potable water
- Corrosion protective coating for clarifiers, tanks, internal and external pipework, valves, fittings, water boxes, manholes, cooling tower pans operating in contact with potable water
- Corrosion protection of submersible pumps
- Concrete repair mortar (combined with Belzona 9241) for potable water tanks and pipework
