Simpson Strong-Tie has introduced the AT-3G, a new, all-weather, hybrid, acrylic anchoring adhesive engineered to deliver a faster-curing, high-strength bond for cracked and uncracked concrete and post-installed rebar connections.

Designed for high performance in extreme environments, the AT-3G adhesive dispenses easily, cures quickly and can be specified for both dry and damp conditions when in-service temperatures range from below freezing (as low as -40 degrees Fahrenheit) all the way up to 320 degrees Fahrenheit.

Offered in single coaxial and side-by-side cartridges for use with standard manual, pneumatic and battery-powered tools from Simpson Strong-Tie, the AT-3G adhesive is easy to prep and apply and has passed the demanding ICC-ES AC308 adverse-condition tests pertaining to reduced and elevated temperatures and long-term sustained loads.

“[The] AT-3G adhesive is a tested, proven and versatile way to provide high anchoring strength in cold weather and adverse conditions where a fast cure is required,” said Simpson Strong-Tie product manager Shea Roche. “With superior sustained load performance and easy application in both dry and damp environments, this new anchoring adhesive provides contractors with a flexible solution for achieving high levels of bond strength across a wide range of job site conditions.”

Code-listed for cracked and uncracked concrete and post-installed rebar connections, the AT-3G adhesive is NSF-approved, IBC-compliant and meets the requirements of Type I/IV, Grade 3, Classes A, B and C under ASTM C881 / AASHTO M235. The 10:1 ratio, two-component adhesive dispenses easily and cures quickly with minimal prep and no power brushing required for hole cleaning. To learn more, visit
