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.
