When KÖSTER 2 IN 1 resin comes into contact with water, it reacts to form a highly elastic foam. When KÖSTER 2 IN 1 resin is injected under dry conditions, it reacts to form a solid body elastic resin. KÖSTER 2 IN 1 remains permanently elastic after reacting. It is therefore able to follow crack movements and seal cracks permanently with an elastic polyurethane solid resin without necessitating follow-up injections. KÖSTER 2 IN 1 is a fast reacting foam for the short term sealing of leaks as well as an elastic solid resin for the permanent sealing of cracks. KÖSTER 2 IN 1 unites two resins in one product.
KÖSTER 2 IN 1 is free of solvents and it is resistant to hydrolysis. KÖSTER 2 IN 1 does not react aggressively when coming into contact with steel or iron, so that a corrosion protection is achieved.
