Product Overview
Water-soluble polyurethane foam water stop is a pre-polymerized ionic chemical grouting material synthesized through a reaction between hydrophilic polyurethane polyols and isocyanates, followed by polymerization with a specific ratio of polymeric MDI. This formulation delivers immediate leakage-sealing effects for water seepage in concrete structures.
Product Features
Excellent hydrophilicity: Rapidly polymerizes upon water contact, disperses and emulsifies to form a high-elasticity solid with sand/cement, instantly sealing cracks for permanent waterproofing.
Adjustable gel time: Consolidation time post-water exposure controllable from seconds to minutes.
High expansion, superior flexibility: Minimal shrinkage, strong substrate adhesion, and broad water-quality adaptability.
Excellent injectability: Applicable even at low temperatures. Single-fluid injection system ensures simple operation and easy cleanup.
Customizable production: Eco-friendly water-soluble polyurethane grout tailored to client specifications.
Safety Precautions
Wear PPE (gloves, mask, goggles) during application. Avoid skin contact. Rinse immediately with water if exposed. Seek medical attention if eye contact occurs.
Solvent-based material: Maintain ventilation and keep away from ignition sources. Prohibit open flames near uncured material.
Clean equipment promptly after use with acetone or xylene.
