E-107 Hydrophobic Polyurethane

  • High expansion

  • Good adhesion

  • Can mix with any liquid substance

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.

E-107-Hydrophobic-polyurethane-03

Feature

  • Immediately after contact with water, the product chemically reacts to expand, effectively preventing leakage.
  • Good toughness、good chemical resistance、good environmental performance.
  • Various basements, tunnels, wells, waterways, sites that need to stop water in a short time manner.
