Elastic PUR-Injection resin for permanent watertight sealing
Sika® Injection-203 is a low viscous, elastic and solvent-free polyurethane injection resin, which cures in both dry and wet conditions to form an elastic, watertight filling and sealing material.
Permanently elastic, can absorb limited movement
No shrinkage in subsequent dry conditions
Due to its low viscosity it can penetrate into narrow cracks starting from 0.2 mm in width
