SY-G201 is a one component hydrophilic polyurethane grouting material which formed by the reaction of composite polyol and isocyanate, and sealed by isocyanate reacts quickly when it meets water, solidifies and expands to seal cracks, then achieving the effect of rapid water sealing. It is milky white elastic colloid after reaction with water, with the advantages of fast speed, high strength, small shrinkage rate, strong permeability resistance, etc., widely used in subway tunnel, water conservancy and hydropower, underground garage, sewer and other waterproof plugging engineering fields.
