Product Description
VPU-1 Hydrophilic Polyurethane Grout Overview
VPU-1 is a single-component hydrophilic polyurethane grouting material formulated from composite polyether polyol reacted with polyisocyanate. This chemical grouting material terminates with isocyanate groups and reacts rapidly with water, solidifying and expanding within closed cracks to achieve quick water stopping. The resulting product forms a milky white elastic colloid with excellent speed, strength, minimal shrinkage, and strong impermeability characteristics.
Key Product Characteristics
- Low viscosity with rapid water reaction, forming impervious elastic colloidal concretion with excellent water sealing performance
- Forms ivory elastic colloidal concretion with high compressive strength, low temperature resistance, good elasticity, and penetration proof quality
- Excellent mixing with water, enabling deep penetration into cracks for thorough sealing by concretion body
- Good dilatability with high water content, excellent water affinity and groutability, with adjustable viscosity and curing speed
- Wide application range for waterproof projects including dams, subway systems, and tunnels
