Description

A 2-part spray- or brush-applied high-performance epoxy coating for erosion and corrosion protection of equipment operating under continuous immersion up to 50°C (122°F). This solvent-free anti-corrosion coating can be easily mixed and applied at ambient temperatures as a one or two-coat system. Its 24 hours overcoating window allows large applications to be quickly completed, reducing downtime.

Due to its capability for high film build in a single coat without sagging and superior erosion resistance, Belzona 1331 is ideally suited to be used as an epoxy pipe lining for the protection of girth welds on internal field joints. This new generation spray-applied, filler-free industrial coating provides the robust protection of a ceramic epoxy coating without causing wear or damage to spray equipment.

  • Outstanding erosion and corrosion resistance under immersed conditions
  • Rapid application by airless spray without wear to spray equipment; can also be brush-applied where required
  • Allows for one or two coat applications with 24 hours overcoat window
  • Capable of high-build application (> 1250 microns) in a single coat without sagging
  • Excellent cathodic disbondment resistance
  • Excellent flexibility, toughness, and impact resistance
  • Outstanding chemical resistance against a wide range of chemicals
  • Available in light colors to aid visibility in dark vessels during application and inspection
  • Application and cure at room temperature – no hot work involved
  • Reduced health and safety risks as it is solvent-free
  • Excellent adhesion to most metal surfaces including carbon steel, stainless steel, and specialist steels
  • Epoxy pipe lining for protection of girth welds on internal field joints
  • Repair of worn and damaged chutes and hoppers
  • Long-term corrosion protection of scrubber units
  • Erosion-resistant coating for leading-edge protection on wind turbine blades.

The industrial coating, Belzona 1331 provides corrosion protection by creating a barrier that prevents a variety of chemicals from permeating the epoxy material and reaching the substrate underneath.  
Corrosion is when a refined metal is converted to a stable form. The causes of corrosion are chemical reactions to other substances such as oxygen and hydrogen which is why water and humidity cause corrosion. In addition, electrical currents, bacteria, and physical stress can all cause metals to corrode.
