Water-swellable water-stop glue is a one-component, solvent-free, water-swellable polyurethane amorphous paste, used for sealing structural joints and steel bars, Leakage around pipes, wires, etc. It has a double sealing and water-stopping function. When water enters the joint, it can use the elasticity of the rubber (to stop water with compressive stress) and the expansion volume of the rubber when exposed to water (to stop water with expansion pressure) to fill the gap and play a water-stopping role.
The unique performance advantages of one-component polyurethane water-swellable water-stop glue make it have a very wide range of application in practical engineering applications. The amorphous paste ensures that it can be suitable for waterproofing joints on irregular base surfaces. It is easy to construct and has strong operability. It is suitable for various joint parts, especially between different materials, where the operating space is small, construction is difficult, moisture is high, and Sealing and water-stopping of pile heads and other parts. When in contact with water, its expansion rate can reach more than its original volume. It can be constructed on vertical surfaces, does not sag, has good durability and excellent chemical stability.
