Introduction

SY-G201 is a one component hydrophilic polyurethane grouting material formed by the reaction of composite polyol and isocyanate. It reacts quickly when meeting water, solidifying and expanding to seal cracks for rapid water sealing. It forms a milky white elastic colloid after reaction, offering high strength, small shrinkage, and strong permeability resistance.

Key Advantages

Fast Reaction: Small viscosity allows water to disperse and react quickly to form an impervious gel.
Good Elasticity: High compressive strength, low temperature resistance, and excellent impermeability.
Well Dispersibility: Penetrates deep into cracks to fill them in all directions.
Hydrophilic: Excellent water-absorbing and irrigation properties.
Eco-Friendly: Non-toxic product suitable for various construction environments.

Application Scenarios

Water tanks, towers, basements, and air raid shelters.
Metal and concrete pipeline wall protection.
Underground tunnels and building foundation reinforcement.
Construction joints and structural crack plugging.
Dams, ports, and hydropower station curtain grouting.
Geological drilling wall blocking and mine water gushing control.
