DESCRIPTION

KÖSTER IN 8 is a water-reactive polyurethane prepolymer. The product only reacts in contact with water and then spontaneously forms a firm, tough, elastic, waterproof polyurethane foam. Contact with water is required for curing and foaming reaction. After the reaction, KÖSTER IN 8 remains viscoelastic and is therefore able to follow crack movements and to permanently waterproof without an elastic solid polyurethane resin re-injection. KÖSTER IN 8 is hydrolysis-resistant. KÖSTER IN 8 reaction can be accelerated by adding KÖSTER IN 8 Accelerator. The quantity of accelerator depends on the desired results. Please adhere to the technical data for further details.
