Sika® Injection-101 RC

Polyurethane flexible injection resin for temporary waterstopping

Sika® Injection-101 RC is a 2-part, polyurethane, low viscous, fast foaming, water-reactive injection resin. It cures to a dense flexible foam. Suitable for use in hot and tropical climatic conditions.

  • Foaming reaction only takes place in direct contact with water
  • Can be injected as a single component system
  • Free foaming expansion up to 40 times
  • Can be accelerated using Sika® Injection-AC10 in cold temperatures (< + 10 °C)

 The data above are laboratory parameters and may deviate depending on the situation and conditions on site.

The reaction speed (foam formation) is influenced by the temperatures of the mixed material, the structure and the contact water, plus the hydrodynamic conditions.

Smaller volumes can be used at a ratio of  Part A : Part B =  1:1 by volume

Ambient air temperature

+5 °C min. / +35 °C max.

Substrate temperature

Application steps

MIXING

Empty Parts A +B into a mixing vessel and mix slowly and thoroughly for at least 3 min (max. 250 rpm) until completely mixed. 

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.
