Single Component Viscoplastic PU-Injection Foam for the Single-Stage Sealing of Water-Bearing Cracks and Joints

KÖSTER KB-Pur IN 7 is a single component polyurethane prepolymer used with 10% catalyst. The product reacts only when coming into contact with water and forms spontaneously a compact, viscoplastic, waterproof polyurethane foam.

KÖSTER KB-Pur IN 7 remains viscoplastic after reacting and is thus able to follow crack movements and to seal permanently without the necessity of subsequent injections with an elastic polyurethane massive resin.

KÖSTER KB-Pur IN 7 is solvent-free and resistant to hydrolysis.
