KOSTER PUR Gel is a solvent-free, water activated polyurethane gel that is NSF approved for use in drinking water environments. Depending on the amount of water added, a highly elastic, waterproof, foam-hydro-gel is formed. Even after dilutions up to 1:10, the material is still resistant to pressurized water. It does not contain free isocyanides and is chemically stable after reacting. It does not contribute to corrosion and does not emit groundwater polluting substances.
Coverage: Dependent on application.
