Elastic PUR-Injection resin for permanent watertight sealing
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
