Product Introduction
It is a one component hydrophobic polyurethane grouting material, formed by the reaction of composite polyol and isocyanate, and sealed by isocyanate. It reacts quickly when it meets water, solidifies and expands to seal cracks, achieving the effect of rapid water sealing. It forms a milky white elastic colloid after reaction with water, generating a water-insoluble foam that waterproofs, plugs leakages, and provides strengthening effects.
Key Advantages
Large Foaming Ratio
The foaming ratio can reach about 25 times, providing excellent water transmission performance and chemical stability.
Strong Consolidation
Rapid chemical reaction in water creates high expansion pressure, forming a tough consolidation body deep within cracks.
Strong Adhesion
Excellent bonding performance with concrete bases and other building materials.
Environmental Friendly
Belongs to non-toxic products, suitable for construction in a variety of environments.
Applications
Construction engineering, municipal engineering, road engineering, tunnel engineering, water conservancy and hydropower engineering, mining engineering, petrochemical engineering, Marine engineering, and other fields.
Frequently Asked Questions
What is the main use of this polyurethane grouting material?
It is primarily used for rapid water sealing and leak repair in subway tunnels, underground garages, sewers, and water conservancy projects.
How does the material react with water?
Upon contact with water, it undergoes a rapid chemical reaction, expanding and solidifying into a tough, water-insoluble foam that seals cracks.
What is the expansion/foaming ratio?
The foaming ratio is significantly high, reaching approximately 25 times (≥2000%) its original volume.
Is the product safe for the environment?
Yes, this product is categorized as non-toxic and environmentally friendly, making it suitable for various construction sites.
What is the shelf life and storage requirement?
The shelf life is 6 months when stored properly in a sealed drum. It should be kept away from moisture until ready for use.
Can it be used for reinforcement?
Yes, besides plugging leaks, the material forms a strong consolidation body that provides a certain level of structural strengthening.
