Belzona 2311 (SR Elastomer)

Fast-Curing, Flexible Repair Composite

A fast-curing, abrasion resistant polyurethane elastomer for high speed emergency repairs, rebuilding and coating of rubber components and metal surfaces

Belzona 2311 (SR Elastomer) is a two-component elastomeric polymer repair and rebuild composite for rubber components.

This easy-to-mix material cures rapidly, without the need for heat, enabling repairs to be carried out with minimal downtime.

Belzona 2311 can be used for both emergency and permanent repairs without the need of specialist equipment. It exhibits high adhesion to many substrates – metallic, plastic or rubber – and once applied, can cure to experience movement in as little as 15 minutes. This makes it Belzona’s fastest curing elastomer.

Ideally designed for fast and small repairs, this flexible material also has exceptional properties to protect it against wear, impact and abrasion.

Key Benefits:

  • Outstanding protection against wear, impact and abrasion
  • Very fast cure for emergency repairs – repaired components back to service almost immediately
  • Cold-curing – no hot work involved
  • Packaged in individual pocket sized sachets for an easy application
  • Excellent adhesion to a wide variety of substrates including natural rubber, nitrile, neoprene, SBR (Styrene Butadiene Rubber), polyurethane, PVC, steel, copper and concrete
  • Outstanding mechanical strength
  • Reduces health and safety risks as it is solvent-free
  • Excellent chemical resistance to a wide variety of chemicals
  • Good electrical resistance
  • Outstanding elongation (up to 450%)
  • Protection against erosion and corrosion

Applications for Belzona 2311 (SR Elastomer) include:

  • Emergency repair of rubber components
  • Repair of rubber coatings on floating hoses to provide long-term abrasion resistance with very minimal downtime
  • Cold-curing alternative to vulcanized rubber repair of worn, split or torn areas of conveyor belts
  • Durable impact and wear protection on pumps volutes and impellers
  • Simple repair of cracks of tyre sidewalls on heavy duty trucks
  • Fast repair of worn gasket seals and rubber rollers
