2 In 1 Crack Injection Resin

Water reactive elastic PU crack injection resin for single and two stage injection of dry and water bearing cracks and joints.

KÖSTER KB-Pur® 2 IN 1 resin can be applied for single-staged sealing of dry cracks in concrete and masonry utilizing a pressurised injection system without necessitating follow-up injections. It can also be used for two-staged sealing of water bearing cracks. It can be used to inject dry and water bearing construction joints and for filling dry or wet voids.

When the resin comes into contact with water, it reacts to form a highly elastic foam. When injected under dry conditions, it reacts to form a solid body elastic resin.

It 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. A fast reacting foam for the short term sealing of leaks as well as a elastic solid resin for the permanent sealing of cracks. KB-Pur® 2 IN 1 unites two resins in one product. Is free of solvents and it is resistant to hydrolysis. Does not react aggressively when coming into contact with steel or iron, so that a corrosion protection is achieved.
