Sika® Injection-101 AP

Polyurethane flexible injection resin for water stopping and waterproofing

Sika® Injection-101 AP is a 2-part, polyurethane, low viscosity, fast foaming, water-reactive injection resin. It cures to form a dense flexible foam.

  • Requires direct contact with water for foaming reaction to commence
  • Can be injected as a single component system
  • Free foaming expansion in contact with water up to 40 times

  1. The data above are laboratory parameters and may deviate depending on the situation and conditions on site.
  2. The reaction speed (foam formation) is influenced by the temperatures of the mixed material, the structure and the contact water, plus the hydrodynamic conditions.
  3. Smaller volumes can be used at a ratio of Part A: Part B = 1:1 by volume
Application steps

MIXING

Empty Parts A + B into a mixing vessel and mix slowly and thoroughly for at least 1 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.
