Product Description
VPU-2 Hydrophobic Oil Grouting Material
VPU-2 is a single-component hydrophobic polyurethane grouting material that reacts with water to expand into a durable foam with excellent waterproofing and reinforcement properties. This versatile material is widely used in subway tunnels, water conservancy projects, basement parking structures, and sewage systems for effective waterproof plugging and structural reinforcement.
Key Characteristics
- Excellent hydrophobic properties with high chemical stability
- Large penetration radius and solidification volume ratio with rapid water reaction
- High expansion pressure for deep crack penetration and tenacious consolidation
- Superior resistance to acids, alkalis, and organic solvents
- Smooth coating surface with wear resistance and anti-mildew properties
- Strong adhesion to concrete and other construction materials
- Adjustable viscosity and curing speed for project-specific requirements
