Koster IN 5 is a solvent-free, low viscosity, 2 component polyurethane for permanently and elastically injecting, filling, and sealing cracks and construction joints.
Koster IN 5 does not react aggressively when coming into contact with steel or iron, so that a corrosion protection is achieved. Due to its slow reaction, the material can be processed for up to 4 hours.
IN 5 is intended for the pressure injection of construction joints via a injection hoses. It can also be used for permanently and elastically sealing dry, moist and water-bearing cracks and joints as well as for solidifying granular soils.
