SikaInject®-471

2-C Low-Viscosity Epoxy Resin

SikaInject®-471 is a 2-component, solvent free, low-viscosity epoxy resin for structural crack repair.

  • Solvent free
  • Low viscosity, deep penetration into fine hairline cracks and cavities
  • Excellent adhesion to dry surfaces
  • Enables structural repair
  • High compressive strength
  • High chemical resistance
  • Resists hydrostatic pressure and blocks penetration of deleterious substances (once fully cured)
  • Can be used as a fluid-grout up to 9 mm thickness
