Sikadur®-52

Low Viscosity Injection Resin

Sikadur®-52 is two part, solvent-free, low viscosity injection-liquid, based on high strength epoxy resin. It is used for substrate temperatures between +5°C and +30°C.

  • Solvent-free
  • Suitable for both, dry and damp conditions
  • Usable at low temperatures
  • Two grades for different climatic conditions (Normal and Long Potlife)
  • Shrinkage free hardening
  • High mechanical and adhesive strengths
  • Hard but no brittle
  • Low viscosity
  • Injectable with single component pumps

Usage

As an injection resin with good adhesion to concrete, mortar, stone, steel abd wood. Sikadur®-52 is used to fill and seal voids and cracks in structures such as bridges and other civil engineering buildings, industrial and residential buildings, e.g. columns, beams, foundations, walls, floors and water retaining structures. It not only forms an effective barrier against water infiltration and corrosion promoting media, but it also structurally bonds the concrete sections together.
