Repair cracks and leaks in large-diameter pipes and fittings with the Weld-On 12711 845 Tan Two-Part Reactive Adhesive Starter Kit. This kit includes two 43ml cartridges of the 845 two-part adhesive, a manual dispensing gun, and six mixing tips. The easy-to-use dispensing gun easily applies adhesive to bonding surfaces with a simple squeeze of the plastic trigger while the static mixing tips eliminate the need for hand mixing and allow for precise application. The high-viscosity, high-strength adhesive features a fast cure time and excellent gap-filling properties, making it an ideal choice for fabricating fittings, joining saddles to pipes, and repairing cracks and leaky pipe valves and fittings. It is specially formulated for PVC and CPVC piping and can also be used to bond ABS, fiberglass-reinforced polyester, concrete, and other materials to themselves or to dissimilar materials. It is outstanding for joining very large sizes of plastic pipes and fittings with loose gaps. It also provides excellent adhesion in peel, tensile, and sheer applications. This high-strength adhesive can be used underwater, and once cured, it can withstand very high pressure and temperatures (-30° to 200°F). Weld-On 845 is not recommended for use on ceramic, PTFE, silicone, polypropylene, polyethylene, and other polyolefins, or joints with an interference fit.
