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.

Usage

  • Sika® Injection-101 RC is used for the temporary waterstopping of high water intrusions in cracks, joints and cavities in concrete, brickwork and natural stonework.
  • To achieve permanent watertight crack sealing, Sika® Injection-201 CE or Sika® Injection-203 should be injected subsequently.
 

Advantages

  • 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.

Application steps

MIXING

Empty parts A and B into a mixing vessel and mix slowly and thoroughly for at least 3 min (max. 250 rpm) until homogeneous, thereby observing the safety precautions. The containers are supplied according to the required mixing ratio of 1 : 1 parts by volume.
Partial quantities can be measured out in separate vessels. After mixing, pour the material into the pump’s feed container, stir briefly and apply within the pot life.
After mixing, pour the material into the pump’s feed container, stir briefly and use within the pot life.

If the substrate and/or ambient temperatures are < +10 °C, Sika® Injection-AC10 can be added to Sika® Injection-101 RC to accelerate the start of expansion.

CLEANING OF EQUIPMENT

Clean all tools and application equipment according to the Product Data Sheet for the Sika®Injection Cleaning System.
