Dural 619PU

PUR INJECTION FOAM FOR TEMPORARILY STOPPING LIVE WATER LEAKS

DURAL 619PU is 2 component low viscosity, solvent free water reactive fast foaming polyurethane injection resin. The product consisting of a base (Part A) and a Catalyst (Part B), reacts with water to form a rapidly expanding dense and flexible foam to immediately stop the ingress of flowing water though a concrete crack in any other or tunnel construction. Increasing the dosage of the catalyst by 10% will reduce the pot life.

Features & Benefits

• Cured foam remains stable
• Resistant to high hydrostatic pressure
• Pot life can be reduced by increasing the dosage of the catalyst
• Foaming reaction starts only when the mixed resin is in contact with water. Unreacted mixed resin will have a pot life of around 6-8 hours ensuring low wastage of mixed materials
• Excellent adhesion to wet substrate
• Rapid expanding foam with a dense cell structure
• Cured foam is non-toxic and can be used in contact with potable water

Applications

• DURAL 619PU has been designed for immediate stoppage of flowing water from concrete cracks or joints and forming a temporary seal prior to the injection of permanent polyurethane. Also used to fill in cavities in brickwork and concrete
