E-107 Hydrophobic Polyurethane

  • High expansion

  • Good adhesion

  • Can mix with any liquid substance

Through PU injection, The single-liquid polyurethane leakage-proof material triggers water repelling after contact with water; the two bodies rapidly expand after reaction to provide leakage prevention.
The biggest feature is that it can react with any water, and can also be used with low-volume catalysts to adjust the foaming speed according to the actual construction needs.

  • Immediately after contact with water, the product chemically reacts to expand, effectively preventing leakage.
  • Durability and resistance to chemical corrosion, capable of withstanding various external environmental factors. It is not easily damaged by water, chemicals, or UV radiation. Moreover, it meets environmental requirements and does not contain harmful substances.
  • E-107 Hydrophobic Polyurethane is suitable for various locations requiring quick water sealing, such as basements, tunnels, wells, and water channels. It can address leakage needs on different materials and surfaces, including concrete, bricks, and metals.
