High-performance polyurethane for cavity filling and backfilling injection 'AGSR-FI'
It reaches final strength in a short time! It is a highly safe material that takes into consideration the environment and ecosystems.
"AGSR-FI" is a polyurethane foam that cures and expands quickly by mixing polyols and modified isocyanates. It reaches its final strength in a short time, allowing immediate use of the tunnel after construction, and it can cure and expand even underwater, making it usable in spring water environments. By utilizing it as a filling material for back cavities of existing tunnels, it helps restore the structural functions inherent to the tunnel and contributes to the extension of the lifespan of existing tunnels. 【Features】 - It reaches its final strength quickly, allowing immediate use of the tunnel after construction. - It can cure and expand underwater, making it usable in spring water environments. - The foam has independent bubbles, so high water-stopping properties are expected after curing. - Its low foam density means that the load on the lining concrete is minimized. - It complies with the "Guidelines for Safety Management of Polyurethane Injection Materials in Mountain Tunnel Construction." *For more details, please refer to the PDF document or feel free to contact us.
basic information
【Other Features】 - Due to the quick cream time (foam start time) after mixing the two components, there is less escape to areas outside the application site, allowing for limited filling and injection. - After foaming and curing, there is minimal volume change such as shrinkage, and it excels in durability and chemical resistance, maintaining quality over the long term. - The high expansion ratio product (40 times expansion) requires less material relative to the size of the cavity (1/40), and the injection equipment is compact, making it easy to transport materials and equipment, and less susceptible to constraints from the working environment such as space. *For more details, please refer to the PDF document or feel free to contact us.
