Koster IN 8
Koster IN 8 is a unique water reacting polyurethane prepolymer (Resin Injection). When in contact with water, Koster IN 8 spontaneously forms a robust, elastic, and waterproof polyurethane foam.
Contact with water is essential for Koster IN 8’s curing and foaming processes. Once the reaction is complete, Koster IN 8 maintains its viscoelasticity, enabling it to track crack movements and provide long-term waterproofing without the need for an additional elastic solid polyurethane resin injection.
Koster IN 8 is a solvent-free product and exhibits resistance to hydrolysis. This attribute further enhances its application potential and durability.
