Sika® Injection-201 CE

Elastic PUR-Injection resin for permanent watertight sealing

Sika® Injection-201 CE is a very low viscous, elastic and solvent-free polyurethane injection resin. In contact with water, a uniform, closed and therefore watertight pore structure forms, which is elastic and flexible.

  • Permanently elastic, can absorb limited movements
  • No shrinkage in subsequent dry conditions
  • Due to its low viscosity it can penetrate into cracks >0.2 mm in width
  • Cured Sika® Injection-201 CE is inert and chemically-resistant
  • Solvent-free
  • In cold temperatures (< +10°C) Sika® Injection-201 CE can be accelerated using Sika® Injection-AC20
  • Can be injected as a one component system

Usage

  • Sika® Injection-201 CE is used for permanent watertight sealing with some flexibility to absorb limited movement, in dry, damp or water-bearing cracks and joints in concrete, brickwork and natural stone
  • Sika® Injection-201 CE can be used for the injection of the SikaFuko®-System (non re-injectable!)
  • For use in water-bearing cracks under hydrostatic pressure, preliminary injection shall be made with Sika® Injection-101 RC
 

Advantages

Application steps

SUBSTRATE PREPARATION

Surfaces of cavities and cracks need to be clean, free of loose particles, dust, oil and any other bond-breaking substances. Any dirt must be blown out by compressed air.

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, 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 into separate vessels.
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-AC20 can be added to accelerate the reaction time.

CLEANING OF EQUIPMENT

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