VPU-2 Oil-Based Polyurethane Grouting Material with 2000-3000% Foaming Capacity and 8-9 MPa Compressive Strength
VPU-2 hydrophobic polyurethane injection material offers superior waterproofing and structural reinforcement. Features include 400-800 mpa.s viscosity, 300-600 second curing time, and excellent chemical resistance. Ideal for tunnels, basements, and water infrastructure projects requiring durable, high-performance sealing solutions.
VPU-2 is a one-component hydrophobic polyurethane grouting material that reacts with water to expand into a durable foam with excellent waterproofing and reinforcement properties. This oil-based polyurethane injection material is specifically designed for demanding construction applications.
- Superior hydrophobic properties with high chemical stability
- Large penetration radius and solidification volume ratio (2000-3000% foaming capacity)
- Rapid reaction with water generates significant expansion pressure for deep crack penetration
- Excellent resistance to acids, alkalis, and organic solvents
- Smooth, wear-resistant coating with anti-mildew properties
- Strong adhesion to concrete and other construction materials
- Adjustable viscosity and curing speed to meet project requirements
