PC-Inject Seal® PU 200

Polyurethane-Based Injection resin foam for temporary Water Leakage Mitigation

PC-Inject Seal® PU 200 is a two-component, low-viscosity, solvent-free, water-reactive polyurethane injection resin that rapidly expands upon contact with water. Consisting of a base (Part A) and a Catalyst (Part B), this product is designed to swiftly create a dense and flexible foam. Its primary function is to effectively seal concrete cracks in tunnels and construction sites, thereby swiftly stopping water flow.

FEATURES

  • The cured foam exhibits remarkable stability.
  • It showcases exceptional adhesion to wet surfaces.
  • Demonstrates resistance to high hydrostatic pressure.
  • Rapidly expands, forming a dense cell structure.
  • Adjusting the Catalyst dosage can reduce the pot life.
  • The cured foam is non-toxic and suitable for use with potable water.
  • The foaming reaction commences upon contact of the mixed resin with water. unreacted resin remains viable for approximately 6-8 hours, reducing material
    wastage.

USES

The PC-Inject Seal® PU 200 is specifically formulated to promptly halt water flow from concrete cracks or joints, creating a provisional seal before the application of a permanent polyurethane grout such as PC-Inject Seal® PU 300 (Flexible gel). Moreover, it serves the purpose of filling voids in both brickwork and concrete structures.
