KOSTER IN 5 is a solvent-free, low viscous polyurethane for elastic filling and sealing cracks and construction joints. KOSTER IN 5 does not react when coming into contact with steel or iron, so that corrosion protection is achieved. Due to its slow reaction, the material maybe injected for up to 4 hours. It is a 2 component system. Once the A and B component are mixed together, the curing begins. Water is not needed for the reaction.
