| Introduction: DOPU-201 is an eco-friendly single component hydrophobic polyurethane grouting material. This chemical grouting material is produced by the reaction of blend polyols and isocyanate, and end-capped by isocyanate. The material can react rapidly with water, its volume expands, to form a water-insoluble foaming. This material can not only waterproof plugging, but also has a certain reinforcement and stabilization effect. It has been widely used in subway tunnels, water conservancy and hydropower, underground garage, sewer and other fields of waterproof leakage plugging. Features: - Good hydrophobicity and chemical stability
- With large permeation radius,solidification volume ratio and high water reaction rate.Reacting with water can release a lot of expansion pressure which push the slurry to diffuse to the depth of the crack to form a rigid consolidation
- Good chemical corrosion resistance against acid, alkali and organic solvents
- The coating is smooth, wear-resistant and free from mold
- Excellent adhesion with concrete base and other building materials
- The viscosity and setting time can be adjusted according to engineering requirements.
Application:- Filling seam sealing and waterproof anticorrosive coating of Water tank, water tower, basement, shelter and other buildings
- Corrosion protection of metal and concrete pipe layer and steel structure
- Foundation reinforcement of underground tunnels and buildings and ground dustproof treatment
- The sealing and strengthening of deformation seams, construction joints and structural cracks in construction projects
- Sealing leakage and reinforcement of ports, wharves, piers, dams and hydropower stations, etc
- Wall protection and leak plugging in geological drilling, selective water plugging in oil exploitation, and water stop-gushing in the mine, etc.
