KOSTER KB-PUR® IN 7 is a water activated polyurethane prepolymer. The product reacts when in contact with water and spontaneously forms a compact, viscoplastic, waterproof polyurethane foam. KOSTER KB-PUR® IN 7 remains viscoplastic after reacting and is able to follow crack movements and seal permanently without the need for follow-up injections with an elastic polyurethane resin. KOSTER KB-PUR® IN 7 is solvent-free and resistant to hydrolysis.
