Product Properties

  • Reduced degree of shrinkage
  • Controlled thermal expansion
  • Increased bending tensile strengths
  • Increased resistance to carbonation
  • The fresh mortar is considerably plasticized
  • Increased chemical and abrasion resistance
  • Lowering the permeability and chloride ingress
  • More economical than Epoxy or Polyester Resin mortar
  • The compressive and flexural strength is increased compared to the reference mix

Areas of Application

  • Bonding slurry between hardened concrete and fresh topping of concrete or mortars
  • For bonding new cementitious materials to existing cementitious substrates on horizontal or vertical surfaces
  • The production of repair mortars, e.g. in the repair and filling of structural concrete in bridge building and civil engineering
  • Cold joints between old and new concrete can be made strong and non-permeable with bonding slurry consisting of Nafufill SBR and cement mortar
  • Second component for Dichtament DS waterproofing system
  • Bonding mortars for bonding of hard-burned bricks, asbestos cement, natural stones, tiles etc.
  • Repairs mortars for mending damaged spots in precast concrete industry, pipelines etc.
  • Improvement of the mechanical characteristics of ready-to-use coarse and fine repair mortars intended for the repair of concrete (such as Zentrifix AS & Nafuquick)
