Description
A durable, 2-part epoxy coating for the long-term protection of concrete and metal surfaces from chemical attack. This solvent-free coating isolates concrete and metal surfaces from aggressive chemicals especially acids and alkalis. It is easy to mix and apply by hand or spray without the need of specialist tools and cures at room temperature.
Key benefits:
- Excellent chemical resistance against a wide range of chemicals
- Easy to mix and apply with no specialist tools
- Reduced health and safety risks as it is solvent-free
- Application and cure at room temperature – no hot work involved
- No shrinkage, expansion or distortion
- Excellent electrical insulator
- Excellent bonding to all rigid substrates including concrete, stone, brick, stainless steel, mild steel, carbon steel and copper
- High compressive strength
Applications for Belzona 4311 (Magma CR1) include:
- Chemical resistant coating for bund areas, chemical spill areas, concrete tank plinths and retaining walls
- Sealing of chemical drains and channels
- Protecting concrete pump bases and casings from chemical spill
- Creation of non-slip walkways in chemical containment areas when combined with aggregate
- Coating of pump impellers and volutes to prevent chemical attack
