E-108 Hydrophilic Polyurethane

  • Good toughness

  • Good chemical resistance

  • Can mix with any liquid substance

It is a hydrophilic single-liquid polyurethane leakage-proof material. After it acts with water, it rapidly expands to form a high-elastic foam to block its cracks, achieving the purpose of stopping water.
According to the actual construction needs, the foaming speed is adjusted to achieve the leak prevention.



  • The higher the resin density, the stronger the tensile strength.
  • Strong elongation and good toughness,good chemical resistance and strong adhesion.
  • Temperature also affects the reaction time with water. The higher the temperature, the faster the reaction time.
  • Various basements, tunnels, wells, waterways, sites that need to stop water quickly, etc.
