AT-3G is a hybrid, acrylic-based adhesive for anchoring threaded rod and rebar into cracked and uncracked concrete. Ideal for cold weather and wet concrete applications, AT-3G dispenses easily and offers a fast curing time for same-day bolt up. It can be specified for a wide range of in-service temperatures, and maintains its strong bond strength in extreme environments for ultimate design and jobsite flexibility. Tested and code compliant with the IBC and IRC, AT-3G hybrid adhesive is easy to install with the conventional blow-brush-blow hole cleaning method.
