KOSTER IN 1 is a polyurethane prepolymer used with 10% catalyst. The system is single component, meaning it reacts when coming into contact with water and forms spontaneously a solid waterproof polyurethane foam. KOSTER IN 1 is solvent and filler-free, resistant to hydrolysis and is suitable for use in potable water areas. When the mixed material comes into contact with water it reacts to form a fine-pored, closed cell foam, stopping and displacing the water.
