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.
