Chenyu - Polyurethane Grouting Material

Polyurethane Grouting Materials is a water-insoluble, single-component grouting material made from a special polyether and isocyanate. Upon contact with water, it disperses, emulsifies, foams, and expands, immediately undergoing a polymerization reaction to form a gel that seals leaks and seals them. This product is available in hydrophilic and hydrophobic polyurethane grouting materials.

Polyurethane grouting fluid (hydrophilic) is a hydrophilic chemical grouting material terminated with isocyanate, produced by the reaction of a complex polyether polyol and a polyisocyanate. It reacts rapidly with water, solidifying and expanding to seal cracks, thereby achieving a rapid water-stopping effect. This product forms a milky white elastic colloid upon reaction with water. It offers advantages such as rapid application, high strength, minimal shrinkage, and strong impermeability. It is widely used in waterproofing and leak-proofing projects such as subway tunnels, water conservancy and hvdroDower projects, underground aaraaes. and sewers.

1. It has low viscosity and quickly disperses and reacts with water to form an impermeable elastic colloidal solid with good leak-stopping and water-stopping properties.
2. It forms a milky white elastic colloidal solid with water, which has the characteristics of high compressive strength, low temperature resistance, good elasticity and good impermeability.
3. The product mixes well with water and can penetrate deep into the cracks. The structural solid body formed after the reaction fills the cracks in all directions.
4. The product has good expansion properties, large water content, good hydrophilicity and pourability. At the same time, the viscosity and curing speed of the product can be adjusted according to project needs.
