TRADECC PC Leakinject Hydrogel 6880 – Single-Component PU Injection Resin

Tradecc PC Leakinject Hydrogel 6880 is a one-component, low viscosity, hydrophilic, MDI based polyurethane injection resin. it reacts with water to form a flexible, closed-cell foam. Developed for application in wet and dry structures and does not need a catalyst.

Applications:

• PC Leakinject Hydrogel 6880 can be used as a waterstop for the sealing of pressurised or non-pressurised leakages and water penetrations in walls, floors, concrete constructions, masonry, tunnels, sewer pipes
• For sealing moist, non-structural cracks, PC Leakinject Hydrogel 6880 must be injected as a 1-component system
• For sealing dry, non-structural cracks, PC Leakinject Hydrogel 6880 must be injected as a 2-component system with, for example, a 1/1 ratio with water

Properties: 

• PC Leakinject Hydrogel 6880 reacts with water, forming a flexible, closed cell polyurethane foam; filling the void and forming a tight, impermeable polyurethane seal
• Due to its flexibility, the foam absorbs somewhat the movement of the crack
• Penetrates deep into fine cracks
• Can be injected pure, directly into a leaking crack, fracture or joint or it can be injected mixed with water (for example in a ratio 1/1)
• PC Leakinject doesn’t need any additional catalyst to react with water. PC Leakinject Hydrogel 6880 can be used as it is
• Reacts with water with the formation of carbon dioxide gas. This gas produces a swelling pressure and the resin expands to a dense, closed cell foam, sealing all water penetrations
• Free expansion: ± 300% (PC Leakinject Hydrogel 6880 / water = 1 / 1)
• Good adhesion to mineral construction materials such as concrete, masonry, mortar, etc
• Good all-round chemical resistance

Storage:

Store in a dark, dry place between +10 °C and +30 °C. PC Leakinject Hydrogel 6880 is moisture sensitive.
