Product Description

Simpson Strong-Tie® 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.

Installation

  • Installation Guide
  • Surfaces to receive adhesive must be clean per approved hole cleaning method.
  • Base-material temperatures must be 23°F (-5°C) or above at the time of installation.
    • Suitable for installation down to 0 F (-18 C) with reductions.
  • To warm cold adhesive, store cartridges in a warm, uniformly heated area or storage container. Do not immerse cartridges in water or use microwave to facilitate warming.
  • Mixed material in nozzle can harden in 2-3 minutes at temperatures of 70°F (21°C) and above.
  • Use only Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair AT-3G adhesive performance.
  • For full instructions, see Adhesive Anchoring Installation Instructions.
