Erosion-Corrosion Resistant Ceramic Coating

Belzona 1321 - Erosion-Corrosion Resistant Ceramic Coating


Belzona 1321 (Ceramic S-Metal) is a two-component, high-strength material for the protection of equipment against erosion-corrosion.

Designed to operate under continuous immersion, up to 60°C (140°F), this solvent-free system has outstanding chemical resistance and will bond to a wide range of substrates. Belzona 1321 can also be used as an injection material for the shimming and bonding of components.


Key Benefits:

  • Long-term erosion and corrosion protection.
  • Excellent bonding to almost any rigid surface including steel, aluminium, copper, brass and glass reinforced plastics.
  • High compressive strength.
  • Excellent chemical resistance against a wide range of chemicals.
  • Reduced health and safety risks as it is solvent-free.
  • No shrinkage, expansion or distortion.
  • Application and cure at room temperature - no hot work involved.
  • Long working life.
  • Simple mixing ratio.

Application Areas:


  • Internal coating for centrifugal and positive displacement pumps.
  • Long-term erosion and corrosion resistance for heat exchangers, water boxes and tube sheets.
  • Protection of butterfly and gate valves, fans and kort nozzles from erosion, corrosion and cavitation.
  • Impingement protection of pipe elbows.
  • High strength structural adhesive for metal bonding.
  • Creation of irregular load bearing shims.
