A high performance, 2-part, static dissipative barrier coating designed to transfer surface build-up of electrostatic charge away from hazardous areas. Furthermore, this solvent-free, conductive coating isolates concrete and metal surfaces from aggressive chemicals, especially acids and alkalis. It is easy to mix and apply without the need of specialist tools and cures at room temperature.

Key Benefits:

  • Low surface resistivity allows the dissipation of electrostatic charge
  • 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 bonding to all rigid substrates including concrete, stone, brick, stainless steel, mild steel, carbon steel and copper
  • High compressive strength

Applications for Belzona 4351 (Magma CR5) include:

  • Static dissipative and chemically resistant coating for primary and secondary chemical containment areas
  • Fuel storage tanks and hydrocarbon tanks where fluid is agitated i.e. pumping and piping and filtration systems
  • Static dissipative coating for refineries and grain silos, highly susceptible to static charge accumulation
  • Static dissipative floor coatings for factories and warehouses
