Hydrophilic polyurethane grouting material DWPU-101
DWPU-101 is a common one-component hydrophilic polyurethane grouting material. The composite polyether polyol reacts with the polyisocyanate to form a hydrophilic chemical grouting material terminated by isocyanate. It reacts rapidly with water, solidifies and expands the closed crack, thereby achieving Quickly stop the water. This product is milky white elastic colloid after reaction with water. It has the advantages of high speed, high strength, small shrinkage and strong impermeability. It is widely used in waterproof tunneling projects such as subway tunnels, water conservancy and hydropower, underground garages and sewers.
