Polyurethane injection resin

Description

Comtech Pure LV is a single component polyurethane injection resin with low viscosity properties; when it is cured it formed impermeable flexible seal.

TYPICAL PROPERTIES:

• Colour : Transparent yellow liquid.
• Density: 1 g/cm³
• Viscosity : 200Mpa.S @ 25ºC

AREA OF APPLICATION:

• Hair cracks where very low viscosity injection resin is needed to allow penetration.
• Moving cracks where Flexibility is required to withstand differential movements.
• To be used in conjunction with Comtech Seal PU1, the high foaming expansion of Comtech Seal PU1 can stop the flowing water then Comtech Pure LV can be used as impermeable permanent seal.
• Wide gaps where it needs to be sealed with stable seamless seal.

ADVANTAGES:

• Forms a permanent sealing with high strength in the crack or joint.
• Fast reacting impermeable seal.
• Penetrates deep in fine cracks.
• Non toxic when contacted with drinking water.
• Can be used in dry and wet cracks.
• 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. Injection using single-component grouting equipment.
6. Cleanup.

STORAGE & PACKING: 4 & 10L tin.
