Hydrophobic polyurethane grouting material DOPU-201

Summary information
DOPU-201 is a common one-component hydrophobic polyurethane grouting material. The composite polyether polyol reacts with the polyisocyanate to form a chemical grouting material which is terminated by isocyanic acid. The material reacts with water and chemically expands, and expands in volume to form a water-insoluble foam. It not only can be waterproof and plugged, but also has certain reinforcement and reinforcement effects. It is widely used in subway tunnels, water conservancy and hydropower, underground garages, Waterproof plugging and reinforcement engineering areas such as sewers.
