Duropur Super HydroPhilic Foam is a low viscosity hydrophilic polyurethane formulation with high elongation properties for sealing leaking cracks or joints in concrete structures with continuous moisture exposure. The single-component system reacts with water to form a foam or gel based on the amount of water encountered. This hydrophilic resin is a MDI based, solvent free formulation. The product may be pumped as a single component or as a dual component system with water.
