A 2-part ceramic filled epoxy coating which provides erosion and corrosion resistance to high temperature equipment operating under immersion up to 120°C (248°F). This solvent-free coating provides excellent resistance to a wide range of aqueous solutions, hydrocarbons and process chemicals. It is easy to mix and can be applied using a stiff bristled brush or applicator.

Belzona 1391 (Ceramic HT) can also be used as a high strength structural adhesive for metal bonding and to create irregular load bearing shims where a high temperature  material is required.

Key benefits:

  • Operates at high temperature under immersed conditions
  • Excellent erosion and corrosion resistance
  • Reduced health and safety risks as it is solvent-free
  • High compressive strength
  • Application and cure at room temperature – no hot work involved
  • Excellent chemical resistance against a wide range of chemicals
  • No shrinkage, expansion or distortion
  • Excellent bonding to many metal surfaces including steel, stainless steel, specialist steels

Applications for Belzona 1391 (Ceramic HT) include:

  • High temperature coatings for process vessels, distillation columns, heat exchangers, clarifiers and scrubber units operating under immersion
  • Protecting pumps, valves, hot water tanks and separators from the effects of erosion and corrosion
  • Protection of pipework from moisture and chemical attack
  • High strength structural adhesive for metal bonding
  • Creation of irregular load bearing shims
