Simpson SET-3G High-Strength Epoxy Adhesive is an epoxy-based anchoring adhesive engineered for reliable, high-strength performance when anchoring threaded rod and rebar into cracked and uncracked concrete. Formulated as a 1:1 ratio, two-component system, this low-odor adhesive mixes to a uniform gray color and installs across a wide range of environmental conditions - including dry concrete, water-saturated concrete, water-filled holes, and submerged concrete - making it a dependable choice for demanding structural anchoring applications. The 56 oz. cartridge is designed for use only with Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions.

Key Features

• Superior bond strengths in high seismic areas - permits ductile solutions for structures assigned to Seismic Design Categories A through F, giving engineers the confidence to specify this adhesive where structural performance is critical.
• Recognized per ICC-ES AC308 for post-installed rebar - supports post-installed rebar development and splice length design provisions, streamlining code compliance on rebar doweling projects.
• Improved sustained load performance at elevated temperature - enhanced design flexibility allows the adhesive to maintain integrity under long-term loading at higher in-service temperatures, reducing risk in thermally demanding environments.
• Extreme temperature range for in-service conditions - specified for all base material conditions when in-service temperatures range from -40 deg. Fahrenheit (-40 deg. Celsius) to 176 deg. Fahrenheit (80 deg. Celsius), meaning one product handles diverse climate and application demands.
• Versatile installation orientations and base material conditions - approved for downward, horizontal, and upwardly inclined including overhead placements in wet or submerged concrete, so crews are not restricted by jobsite conditions.
• Vacuum-drill bit compatible without additional hole cleaning - approved for installation with multiple vacuum-drill bit systems without further hole cleaning (see ESR-4057 for approved systems), saving time and labor steps on the jobsite.
• Tested to rigorous industry standards - verified in accordance with ICC-ES AC308 (ESR-4057), ACI 355.4, and applicable ASTM test methods, providing documented proof of performance for submittal and inspection purposes.
• Manufactured in the USA using global materials - produced domestically, supporting projects with domestic manufacturing requirements.

Why This Product

• One adhesive for virtually every concrete anchoring condition - SET-3G is formulated to perform in dry, water-saturated, water-filled, and submerged concrete, eliminating the need to source different products for varying site conditions and simplifying procurement for mixed-condition projects.
• Code-ready documentation for structural and seismic applications - with ICC-ES AC308 recognition (ESR-4057) and ACI 355.4 testing, this epoxy adhesive arrives with the third-party validation inspectors and engineers require, reducing time spent sourcing compliance documentation.
• Engineered for long-term reliability under heat and load - improved sustained load performance at elevated temperature means the bond maintains its design strength over time even in thermally challenging installations, giving specifiers confidence beyond initial installation.
• Low-odor formula that installs cleanly and consistently - the uniform gray color when properly mixed gives installers immediate visual confirmation of correct mixing, while the low-odor formulation makes it more manageable in enclosed or occupied jobsite environments.

Frequently Asked Questions

What mixing nozzle should be used with SET-3G?

Use only Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions. Modification or improper use of the mixing nozzle may impair SET-3G adhesive performance.

Can SET-3G be used in wet or submerged concrete conditions?

Yes. SET-3G is suitable for use in dry concrete, water-saturated concrete, water-filled holes, and submerged concrete, making it highly versatile for a wide range of jobsite conditions.

Is SET-3G approved for use in high seismic areas?

Yes. SET-3G delivers superior bond strengths that permit ductile solutions in high seismic areas and is qualified for use in structures assigned to Seismic Design Categories A through F.

Does SET-3G require additional hole cleaning when used with vacuum-drill bit systems?

SET-3G is approved for installation with multiple vacuum-drill bit systems without further hole cleaning. Refer to Code Report ESR-4057 for the list of approved systems.
