It is a functional material that can quickly stop water and block leaks. It utilizes the characteristic of isocyanate groups in polyurethane prepolymers reacting with water to release carbon dioxide. When the sealant is injected into the leaking area, the material reacts rapidly with water to form a solidified body, thereby reducing or stopping the water leakage.
Product Features
◆ This product is a two-component polyurethane injection grouting and leak-stopping material, consisting of a main agent and a promoter.
◆ The slurry reacts rapidly and foams upon contact with water.
◆ The reaction time can be adjusted by the amount of promoter used, generally controllable within tens of seconds to several minutes of curing.
◆ High foaming rate, the maximum free foaming rate can reach 40 to 60 times.
◆ The solidified body has good impermeability, maintains its original shape permanently in water, and has low-temperature resistance.
◆ It has strong adaptability to water quality.
