The Simpson Strong-Tie ET3G10 epoxy anchoring adhesive is an 8.5-ounce two-component epoxy cartridge for anchoring threaded rod and rebar into concrete and masonry. This is an anchoring adhesive designed for doweling and adhesive anchor installation in cracked and uncracked concrete and masonry. Model Number ET3G10. If you need a cartridge-size adhesive for structural anchoring work, this is the format aimed at smaller jobs, punch-list installs, and crews that want cartridge convenience instead of bulk dispensing equipment.

ET-3G uses a 1:1 epoxy mix and is suitable for static and seismic loading conditions based on the manufacturer data. In practical terms, that means it is made for serious anchor installations, not light patch work or generic adhesive duty. It is intended for threaded rod anchoring and rebar doweling, and it is rated for horizontal, vertical, and overhead applications, which matters when the work is not limited to flat slab conditions.

One of the most useful things about this adhesive is where it can be used. The base materials are concrete and masonry, both cracked and uncracked, and the listed base material conditions are dry and water-saturated. That gives the Simpson Strong-Tie ET3G10 epoxy anchoring adhesive a broader working envelope than products that need ideal, dry conditions to perform as intended. For field work, that flexibility can save a trip and keep the install moving.

Working time is another big reason to choose this product. The published gel time is 50 minutes at 70 degrees Fahrenheit, with cure time listed at 24 hours at that same temperature. At 50 degrees Fahrenheit the gel time stretches to 100 minutes and full cure moves to 72 hours. At 110 degrees Fahrenheit the gel time drops to 18 minutes. That kind of schedule matters because it tells you whether this adhesive fits careful anchor placement, rebar doweling, or hotter weather installs where some products start getting away from you too fast.

The cartridge format on ET3G10 is also straightforward. This specific version is the 8.5-ounce single cartridge, and the known package contents include one EMN22i mixing nozzle and one extension. That makes it a more ready-to-run option for single-anchor or lower-volume work, especially when compared with larger cartridge sizes and bulk kits that may require different dispensing gear or separate nozzle purchases.

On the performance side, ET-3G is a non-sag epoxy with 3 grams per liter VOC and a teal mixed color to help verify proper mixing. Manufacturer data also lists a 13,000 psi compressive yield strength after 7-day cure, which helps explain why it is positioned for anchoring work rather than general-purpose bonding. The in-service temperature range of negative 40 degrees Fahrenheit to 150 degrees Fahrenheit adds confidence once the installation is complete and exposed to seasonal swings.

Jobsite practicality is solid here too. Simpson notes easy hole cleaning with no power brushing required, and the product has a 24-month shelf life when unopened and stored between 45 degrees Fahrenheit and 90 degrees Fahrenheit. For contractors managing van stock or warehouse inventory, that longer shelf life is not a throwaway spec. It means less waste and fewer half-forgotten cartridges that age out before the next job.

Who should buy it? Concrete contractors, general contractors, structural retrofit crews, DOT work crews, and anyone handling adhesive anchoring or rebar doweling in concrete or CMU. Serious DIY users can use it too, but this is clearly a pro-grade anchoring adhesive meant for code-conscious installs and predictable performance. If your work calls for a small cartridge with included nozzle and extension, and you need compatibility with the Simpson Strong-Tie CDT10S dispensing tool, ET3G10 is the practical size to grab.

Small Cartridge, Serious Anchoring Work

The Simpson Strong-Tie ET3G10 epoxy anchoring adhesive makes sense when you need code-minded anchor performance in a cartridge size that is easier to carry, load, and use on smaller runs.

• Who it's for: Contractors and serious users installing threaded rod or rebar in concrete or masonry, especially when the job does not justify a larger bulk system.
• Why it stands out: It covers cracked and uncracked concrete and masonry, works in dry or water-saturated conditions, and gives you a useful working time instead of rushing every placement.
• Worth knowing: This is adhesive-anchor material, not a general construction adhesive, and you need the right dispensing tool and proper Simpson Strong-Tie mixing nozzle setup to use it as intended.

• What is ET3G10 used for? It is used for anchoring threaded rod and rebar into cracked and uncracked concrete and masonry.
• Can it be used in damp conditions? Yes. Manufacturer data lists dry and water-saturated base material conditions.
• How long is the working time? At 70°F, the published gel time is 50 minutes. Working time changes with temperature.
• What dispensing tool does this cartridge use? The ET3G10 cartridge is listed as compatible with the Simpson Strong-Tie CDT10S dispensing tool.
