LW Hydrophilic polyurethane chemical grouting material
LW is a polyurethane material of the Japanese Hisol type. It is a hydrophilic chemical grouting material synthesized by the reaction of compound polyether polyols and polyisocyanates, with isocyanate as the end-capping reagent. It is a fast and efficient anti-seepage and plugging material. Compared with Hisol, this product has been improved in environmental protection, and it is more friendly to the environment. The product can quickly emulsify to form a gel when exposed to water, which is widely used in the anti-seepage treatment of large-flow water gushing, water leakage, and movable cracks in various engineering.

LW Hydrophilic polyurethane chemical grouting material
◆Brief Introduction
LW is a polyurethane material of the Japanese Hisol type. It is a hydrophilic chemical grouting material synthesized by the reaction of compound polyether polyols and polyisocyanates, with isocyanate as the end-capping reagent. It is a fast and efficient anti-seepage and plugging material. Compared with Hisol, this product has been improved in environmental protection, and it is more friendly to the environment. The product can quickly emulsify to form a gel when exposed to water, which is widely used in the anti-seepage treatment of large-flow water gushing, water leakage, and movable cracks in various engineering.
◆Advantages
· The viscosity is relatively small, the hydrophilicity is good, and it can react rapidly with water to form an impermeable gel;
· It can be operated underwater, and grouting can be carried out in the case of water seepage or water gushing;
· The consolidation body of the product has elasticity, which can be effectively adapted to the waterproof treatment of deformation cracks;
· The consolidation body of the product has an excellent performance in low-temperature resistance, and can produce a secondary expansion in contact with water, with the elastic expansion waterproof function;
· The product has good performance in environmental protection, is actually non-toxic, and can be applied to more working conditions;
· The product is single-component packaging and can be used after opening the barrel, without requiring for complicated preparation;
· Mixed grout with different strengths and water expansion multiples can be prepared with HW as required.
◆Scope of use
· Anti-seepage and plugging treatment of various buildings in sectors including transportation, municipal administration, construction;
· Seepage prevention treatment for concrete expansion fissures, cracks, and construction crevices in water resources and hydropower engineering;
· The foundational anti-seepage or curtain grouting treatment of various buildings;
