Industry Standard: JC/T 2041-2010, “Polyurethane Grouting Materials.”
Product Features
- When the slurry comes into contact with water, it emulsifies and foams, immediately triggering a chemical reaction that forms a waterproof, elastic, gel-like solid with excellent water-stopping properties.
- The elastic, gel-like solid formed after the reaction exhibits good elongation, elasticity, impermeability, and low-temperature resistance, and retains its original shape in water over long periods.
- It has good water solubility; when mixed with water, it has low viscosity and good workability. The set product is harmless to humans, non-toxic, and non-polluting when immersed in water.
- When the slurry comes into contact with water, it reacts to form an elastic gel-like substance while releasing CO₂ gas; driven by the gas pressure, the slurry can be further forced into the voids within the structure, exhibiting the characteristic of secondary permeation.
- The slurry has good swelling properties, high water-holding capacity, and excellent foaming properties, as well as good hydrophilicity and workability.
