It is easy to mix and apply by hand or spray without the need of specialist tools and cures at room temperature.

  • 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
  • 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

QUESTIONS & ANSWERS

Belzona engineers chemical-resistant coatings which are epoxy-based liquid or paste-grade coatings that can provide a barrier between harsh acids and alkalis and the substrate. The coating protects the substrate from the chemical attack and endures the chemical attack instead.

The mixing ratio of the high-performance coating, Belzona 4311 (Magma CR1) is 6:1 (Base: Solidifier) by weight and 3:1 (Base: Solidifier) by volume. Please see the Product Specification Sheet (PSS) for more information. Belzona 4311 (PSS)
To apply the anti-corrosion coating, Belzona 4311 (Magma CR1), the surface must be clean, firm, and dry. In addition, it must be free of rust, paint, and other surface coatings and contaminants. Condition the area using Belzona 4911 (Magma TX Conditioner). To mix the material, add the entire contents of the Belzona 4311 (Magma CR1) Solidifier component to the Base unit. Then, mix thoroughly until a completely homogenous liquid is achieved. After, apply the material using a short-bristled brush or a squeegee to the prepared surface. A second coating can be applied as soon as possible to do so without disturbing the first coat. Finally, allow the product to cure. Please see the Instructions for Use (IFU) for more information.
