Belzona 1311 (Ceramic R-Metal)

Belzona 1311 (Ceramic R-Metal)


A 2-part epoxy-based repair composite designed for metal repair and protection against the effects of erosion and corrosion. This solvent-free repair composite has excellent chemical resistance and will bond to all metals and most other rigid surfaces. It is easy to mix and apply without the need for specialist tools and it cures at room temperature eliminating the need for hot work. It is ideally suited to be overcoated with Belzona 1321 (Ceramic S-Metal) to ensure long-lasting performance.

Belzona 1311 (Ceramic R-Metal) can also be used as a high strength structural adhesive for metal bonding and to create irregular load bearing shims.

Key benefits:

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

Applications for Belzona 1311 (Ceramic R-Metal) include:

  • Rebuilding and geometry reconstruction of centrifugal and positive displacement pumps damaged by erosion and corrosion
  • Pit fill and resurface of heat exchangers, water boxes and tube sheets
  • Repair of butterfly and gate valves, fans and kort nozzles deteriorated as a result of erosion, corrosion and cavitation
  • Repair of pipe elbows damaged by impingement
  • High strength structural adhesive for metal bonding
  • Creation of irregular load bearing shims
