Sika® Injection-101 RC

Flexible PUR-Injection foam for temporary waterstopping

Sika® Injection-101 RC is a low viscous, fast foaming and solvent-free water-reactive polyurethane injection foam resin, which cures to a dense flexible foam with a fine cellular structure.

  • No reaction takes place unless it is in direct contact with water.
  • Sika® Injection-101 RC can be injected as a single component system.
  • The free foaming expansion in contact with water is up to 40 times.
  • The reaction speed (foam formation) is influenced by the temperatures of the mixed material, the structure and the contact water, plus the hydrodynamic conditions.
  • In cold temperatures (< + 10°C) Sika® Injection-101 RC can be accelerated using Sika® Injection-AC10.
