ECMAGROUT PU F 260
TWO COMPONENT, HYDROPHILIC, FAST CURING POLYURETHANE INJECTION SYSTEM STOPPING WATER LEAKAGES FORMING A FLEXIBLE FOAM BUT ALSO WITH A SPECIAL FEATURE: REACTING QUICK (20 SECONDS) AND EXPAND TO A FLEXIBLE FOAM FOR ANOTHER 12 – 15 MINUTES
ECMAGROUT PU F 260 is a two component, hydrophilic, 100% MDI based, solvent and phthalate free, fast reacting polyurethane injection system with dual performance
a. when mixed without adding a catalyst, the cream time is around 20 seconds and it expands 2 – 3 times during the next 12 -15 minutes (gel time) making it suitable for the repair of leaking expansion joints or for application in injection hoses. b. when Catalyst F is added, it will be a very fast reacting water stop system forming a flexible foam. Mixing ratio 1:1 in volume.Advantages
• Deeper penetration to fine cracks due to low exceptional low viscosity • The cured material remains flexible and stable after curing • Suitable for hot and cold climates • Good adhesion to the substrate • Can withstand high hydrostatic pressures • A pneumatic 2 or 3 component injection pumps should be used • The reaction time is almost independent from the amount of water to a maximum ratio F 260 to water 1:5 in the structure. • The formed foam will expand and fixes itself into the structure. • Suitable for applications where fluctuating groundwater levels are encountered. • 100% MDI based and no TDI in it. • The cured material is non toxic • The system is suitable for use in contact with potable water
Uses
• Preventative or remedial water proofing of structures. • Shutting off heavy water leakages • Repairing expansion joints • Seal off wet, moist and water containing structures • For sewer repair and manhole repair, manhole etc. • Consolidation of loose or unstable soil
