Product Description
Product introduction:
LW Hydrophobic polyurethane chemical grout is a kind of one component and excluding water material, which is formed via polyisocyanates and polyether polyol reacted under certain conditions. When grouting, NCO perssad meet water, the reaction of chain extension, branching, cross linking and solidification are produced, therefore, stop water rapidly and reinforce concrete effectively. Meanwhile heavy expansion pressure is generated so that to make the grout diffused again. Accordingly, push the grout forward to permeate crack and hole deeply. So it has enough scope of diffusion and solidification.

Specification
Characteristic:
1.Rapid reaction, foaming, solidification are generated after meeting water. adjusting gel time by adding catalyst.
The gel time is usually controlled within 10 seconds.
2.High strength. Under hermetic condition, the compressive strength can be 17-20Mpa in 4 hours.25-30MPa compressive strength and 3MPa bonding strength can be reached in 24 hours.
3.Big expansion ratio. Since foaming, the expansion ratio can be 20 twice.
4.The grout is single component with convenient operation.
5.Steady indurate chemical construction. Good property of bearing chemical resistance.
6.No corrosion to steel.
