Dural 620PU

FLEXIBLE POLYURETHANE INJECTION RESIN FOR PERMANENT SEALING WATER LEAKS

DURAL 620PU is 2 component low viscosity Polyurethane injection resin, used for grouting, and sealing of water bearing cracks and fissures in concrete and brickworks. The resin is solvent free and starts to react and harden to form a flexible and elastic gel when both components are mixed. In the presence of water, the mixed resin forms a flexible resin seal. DURAL 620PU should be used in conjunction with Dural 6PU to stop the flow of live leaks and then seal the crack.

Features & Benefits

• Excellent adhesion to dry and wet substrate
• Cured resin remains stable and does not shrink over time
• Resistant to high hydrostatic pressure and forms a permanent seal
• Extremely low Viscosity. Ability to penetrate fine cracks under pressure
• Forms a permanent seal which is highly elastic and flexible. Can accommodate movements in concrete
• Remains flexible at extremely low temperatures
• Cured gel is chemically inert and nonhazardous to environment
• Cured gel is non-toxic and can be used in contact with potable water
• The hardened gel/foam remains flexible. Can accommodate movement in concrete
• Form a hydrophobic foam when it meets water in the cracks or fissures to force the water out from the structure

Applications

• Dural 620PU is formulated to provide a permanent, flexible seal in water bearing cracks and fissures in concrete, blockwork, and brickwork. This can also be used to seal dry cracks and joints in concrete where movement is expected and used for injecting non-re-injectable hoses used in concrete joints.

Packaging

DURAL 620PU is supplied in the following packings: 2 Litre kit & 5 Litre kit (1 : 1 ratio by Volume)
