Polyurethane injection foam

Description

Comtech Seal PU1 is a single component polyurethane injection resin with low viscosity properties; it reacts with water forming a semi rigid hydrophobic seal.

TYPICAL PROPERTIES:

• Colour : Transparent brown liquid.
• Free expansion: up to 3500 %
• Density: 1.02-1.1 g/cm³
• Viscosity : 250Mpa.S @ 25ºC

AREA OF APPLICATION:

Water sealing of cracks and big gaps in walls, floors, concrete constructions. It has the property of fast reacting to semi rigid PU foam once contacted with water.

ADVANTAGES:

• Forms a permanent sealing with high strength in the crack or joint.
• Fast reacting semi rigid PU foam used as a water stop for sealing of leakages or to stop active water leaks with a high flow and/or high hydrostatic pressure.
• Penetrates deep in fine cracks.
• Does not shrink after curing.
• Non toxic when contacted with drinking water.
• Excellent adhesion to mineral construction materials (such as Concrete, cement, brick), metal and certain plastics.
• It is chemically resistant against water, weak acids and alkali, mineral oils, fungus and bacteria, ground water, sea water and petroleum products.

APPLICATION METHOD:

1. Clean surfaces.
2. Drill injection holes.
3. Insert injection packers.
4. Flush crack, if necessary
5. Injecteion using single-component grouting equipment.
6. Cleanup
