Consumption N/A

Sika® Injection-201 CE is a very low viscous, elastic and solvent-free polyurethane injection resin. In contact with water, a uniform, closed and therefore watertight pore structure forms, which is elastic and flexible.

  • Permanently elastic, can absorb limited movements
  • No shrinkage in subsequent dry conditions
  • Due to its low viscosity it can penetrate into cracks >0.2 mm in width
  • Cured Sika® Injection-201 CE is inert and chemically-resistant
  • Solvent-free
  • In cold temperatures (< +10°C) Sika® Injection-201 CE can be accelerated using Sika® Injection-AC20
  • Can be injected as a one component system
