Simpson ET-3G 56 oz. Epoxy Adhesive Cartridge is a two-component, high-solids, epoxy-based anchoring system from Simpson designed for reliable general anchoring of threaded rod and rebar into cracked and uncracked concrete and masonry. With a generous 50-minute working time at 70 deg. Fahrenheit (21 deg. Celsius) and compatibility with both dry and water-saturated base material conditions, this adhesive delivers consistent, dependable performance across a wide range of anchoring and doweling applications.

Key Features

• Ideal for general doweling and threaded rod applications - covers the most common structural anchoring tasks in concrete and masonry with a single, versatile adhesive system.
• Extended working times at elevated temperatures - gives installers more time to position anchors correctly before the adhesive sets, reducing costly errors on warm-weather jobsites.
• Code listed under the IBC/IRC for cracked and uncracked concrete per ICC-ES ESR-5334 - provides the documented compliance needed to satisfy inspectors and engineers on regulated projects.
• Two-year shelf life for unopened cartridges stored between 45 deg. Fahrenheit (7 deg. Celsius) and 90 deg. Fahrenheit (32 deg. Celsius) - reduces waste and keeps inventory usable for longer between projects.
• Easy hole cleaning - no power-brushing required - simplifies installation prep and speeds up the overall anchoring process without additional equipment.
• Suitable for use in dry or water-saturated concrete - eliminates the need to wait for base material to dry before proceeding, keeping projects on schedule.
• Teal mixed color - provides a clear visual confirmation that the two components have blended properly before application, reducing the risk of installation error.
• 56-oz. side-by-side cartridge format - delivers a larger volume of adhesive per cartridge, making it well-suited for high-volume anchoring work where efficiency matters.
• Use only Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions - ensures proper material mixing and protects adhesive performance throughout the full installation.

Why This Product

• Versatile anchoring across multiple base materials - approved for use in cracked and uncracked concrete and masonry under both dry and water-saturated conditions, making it a dependable choice for varied jobsite environments without switching products.
• Code compliance built in - ICC-ES ESR-5334 listing under the IBC/IRC for cracked and uncracked concrete means contractors and engineers can specify this epoxy anchoring adhesive with confidence on code-required projects.
• Simplified installation process - no power-brushing required for hole cleaning, and the teal mixed color confirms correct component blending, helping crews work faster and with fewer steps between drilling and setting anchors.
• Long working time supports accuracy on the job - the 50-minute working time at 70 deg. Fahrenheit (21 deg. Celsius) gives installers the window they need to set threaded rod and rebar correctly, even on larger or more complex anchoring applications.
