ICT Liquid Steel™ 1550 and Liquid Steel™ 2200 GEL are both two-component epoxy resins, packaged in a side by side cartridge that provides point-of-use application to save time, material and minimize health hazards. They have been specifically designed for crack injection, which is convenient, quick and easy to use, and affords the contractor maximum efficiency. Both cartridges are designed to be used with a side by side, dual epoxy applicator gun that is adaptable to both the 1550 & 2200 cartridges. Each cartridge comes with mixing tips through which the two parts combine to form the strong bonding epoxy that will fill and weld concrete cracks, as well as suit other construction site uses. Liquid Steel™ 2200 GEL is a non-sag, high viscosity, fast set epoxy resin that is best for larger cracks (> 1/4” in width), vertical walls, or for doweling or anchoring objects into concrete. Either product forms a permanent weld with concrete and is a great tool to begin the resurfacing of an old slab. In addition, 2200 GEL also works great for the following applications: concrete construction, crack Repair, tanks, new to old concrete, bridges, culverts, wood, steel, fiberglass adhesive, grout bolts & dowels.
