Comtech Pure LV is a single-component polyurethane injection resin with low viscosity; when cured, it forms an impermeable, flexible seal.
TYPICAL PROPERTIES:
- Colour : Transparent yellow liquid.
- Density: 1 g/cm³
- Viscosity: 200 MPa.s @ 25ºC
AREA OF APPLICATION:
- Hairline 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, and then Comtech Pure LV can be used as an impermeable permanent seal.
- Wide gaps need to be sealed with a stable, seamless seal.
ADVANTAGES:
- Forms a permanent, high-strength seal in cracks or joints.
- Fast-reacting impermeable seal.
- Penetrates deep into fine cracks.
- Nontoxic when contacted with drinking water.
- It 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 to water, weak acids and alkalis, mineral oils, fungi and bacteria, ground water, sea water, and petroleum products.
APPLICATION METHOD:
- Clean surfaces.
- Drill injection holes.
- Insert injection packers.
- Flush the crack, if necessary.
- Injection using single-component grouting equipment.
- Cleanup.
