Product Description
The Simpson Strong-Tie AT3G30 AT-3G 28 oz. High-Strength Hybrid Acrylic Anchoring Adhesive is a hybrid, acrylic-based adhesive engineered for anchoring threaded rod and rebar into cracked and uncracked concrete. Formulated to perform in cold weather and wet concrete conditions, AT-3G dispenses easily and delivers a fast curing time for same-day bolt up. It can be specified for a wide range of in-service temperatures and maintains strong bond strength in extreme environments, offering ultimate design and jobsite flexibility. Tested and code compliant with the IBC and IRC, AT-3G supports easy installation using the conventional blow-brush-blow hole cleaning method - no power brushing required. This cartridge is also the direct replacement for the discontinued AT-XP30.
Key Features
- Fast cure in cold weather down to 0 deg. Fahrenheit (-18 deg. Celsius) - lets crews install and achieve same-day bolt up even in freezing job site conditions, eliminating costly weather-related delays.
- Hybrid acrylic formula for cracked and uncracked concrete - expands your anchoring options across a broad range of structural conditions without switching products.
- Recognized per ICC-ES AC308 for threaded rod and rebar anchoring - covers post-installed rebar development and splice length design provisions, giving engineers and inspectors a clear, code-backed specification path.
- Conventional blow-brush-blow hole cleaning - no power brushing required - simplifies prep work and reduces the equipment needed on site, saving time and labor.
- Compatible with grout-filled CMU construction, oversized holes, and diamond core-drilled holes - provides broad application flexibility so one adhesive can address multiple anchoring scenarios on the same project.
- Tested in accordance with ICC-ES 308, ACI 355.4, and applicable ASTM test methods - provides verified, independently tested performance data that supports engineer-of-record approval and code submittals.
- 28 oz. side-by-side cartridge includes AMN19Q mixing nozzle - arrives ready to dispense with the correct mixing nozzle already included, reducing the risk of pairing errors that could impair adhesive performance.
Why This Product
- Built for the most demanding installation conditions - the AT-3G hybrid acrylic formula handles wet concrete, sub-freezing temperatures, and a wide range of in-service environments where standard adhesives may fall short, giving crews and engineers greater confidence on challenging projects.
- Speeds up the schedule with same-day bolt up - fast cure times mean anchors can be loaded the same day they are set, helping contractors meet tight timelines without sacrificing bond strength or code compliance.
- Simplifies the specification and approval process - compliance with IBC and IRC and recognition per ICC-ES AC308 means the AT-3G arrives with the documentation engineers, inspectors, and project owners need, reducing back-and-forth on submittals.
- Drop-in replacement for the discontinued AT-XP30 - existing project specs or purchasing histories referencing AT-XP30 can transition directly to AT3G30 without redesign, keeping procurement and field operations moving without interruption.

Frequently Asked Questions
What dispensing tools are compatible with the AT3G30 adhesive cartridge?
Install using the Simpson Strong-Tie ADT30S, ADTA30P, or ADTA30CKT dispensing tools. Use only Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions - modification or improper use of the mixing nozzle may impair AT-3G adhesive performance.
Can the AT-3G adhesive be used in very cold weather or freezing temperatures?
Yes. AT-3G is specifically designed for cold weather applications, with base material installation temperatures down to 0 deg.F (-18 deg.C). It also offers fast curing times, making it ideal for applications where same-day bolt up is required.
What hole cleaning method is required when using AT-3G adhesive?
AT-3G uses the conventional blow-brush-blow hole cleaning technique with a wire brush - no power brushing is required. A vacuum may also be used in lieu of compressed air for hole cleaning.
Is the AT-3G adhesive code compliant, and what standards has it been tested to?
Yes. AT-3G is recognized per ICC-ES AC308 for threaded rod and rebar anchoring, including post-installed rebar development and splice length design provisions. It has been tested in accordance with ICC-ES 308, ACI 355.4, and applicable ASTM test methods, and is compliant with the IBC and IRC.
