one component void filling type chemical PU grout - LW-8020

Description:

Hydrophilic polyurethane chemical grouting material is a kind of rapid and high efficiency chemical grouting material used for seepage-proofing and leaking stoppage.It has unique sealing effect for a great quantity water burst and leaking in variety of projects,which has been applied widely in plenty of projects.The mentioned achievement has ever won National Process Awards in Science and Technology.

Advantage:

1. Foam fast, high foam ratio, filling efficiency, effectively reduce the overall maintenance cost.
2. solvent-free, high flash point, especially for enclosed roadway construction.
3. Non-combustion, surface temperature is 50-60 degrees, the internal reaction temperature below 90 degrees, is particularly suitable for use in coal mines.
4 .To the rock, concrete and other construction base surface has a good bond strength

Range of application:

1. Fill broken coal or rock in the holes, crack in tunnels caverns and more
2. Seal coal mined area and abandoned roadway, to prevent air leakage, filling the working face or roadway holes, to prevent gas accumulation

Technology Data:

STORAGE:

Storage at indoor room temperature. Temperature above 50oC may cause accelerate
formation of insoluble solid. Good housekeeping is essential in areas where chemical spillage
is likely to occur.
