VPU-2 Hydrophobic Oil Grouting Material for Concrete Waterproofing - 400-800 mpa.s Viscosity, 2000-3000% Foaming Capacity
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 material is insoluble in water and widely used in demanding construction and infrastructure projects.
- Excellent hydrophobic properties with high chemical stability
- Large penetration radius and solidification volume ratio with rapid water reaction
- Generates significant expansion pressure for deep crack penetration
- 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
- Customizable viscosity and curing speed for project requirements
