  • Exhibits excellent adhesion to manually prepared damp, oil contaminated and underwater substrates
  • Rapid cure even at low temperatures allows for emergency in-situ repairs without the need for hot work
  • Excellent mechanical properties ensuring durability and longevity in service
  • Simple 1:1 volume mix ratio makes it easy to mix and apply with no need for specialist tools
  • Ideal for repair kits and emergency repair due to its versatility in use
  • Reduced health and safety risks as it is solvent-free
