Simpson ET-3G 8.5 oz. Epoxy Adhesive Cartridge from Simpson is a two-component, high-solids, epoxy-based anchoring system engineered for general anchoring of threaded rod and rebar into concrete and masonry - both cracked and uncracked. Suitable for dry or water-saturated base material conditions, this cartridge delivers reliable, code-compliant adhesive anchoring performance across a wide range of structural and construction applications. Each cartridge ships ready to use, complete with one EMN22i mixing nozzle and one nozzle extension, and is dispensed using the Simpson CDT10S dispensing tool.

Key Features

• Ideal for general doweling and threaded rod applications - gives contractors and builders a single, versatile adhesive solution for the most common concrete and masonry anchoring tasks.
• Extended working times at elevated temperatures - reduces time pressure on the job site, allowing careful placement and adjustment before the adhesive sets.
• Code listed under the IBC/IRC for cracked and uncracked concrete per ICC-ES ESR-5334 - meets code requirements without additional engineering review, streamlining project approvals.
• 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 lets you stock adhesive with confidence for future jobs.
• Easy hole cleaning - no power-brushing required - saves time and eliminates the need for extra equipment during installation prep.
• Suitable for use in dry or water-saturated concrete - provides dependable adhesion even in challenging or wet job site conditions.
• Teal mixed color - provides instant visual confirmation that the two-component adhesive is properly blended before application.
• Includes one EMN22i mixing nozzle and one nozzle extension - arrives ready for immediate use, including in hard-to-reach or deep-hole anchoring situations.

Why This Product

• No-hassle surface prep - because power-brushing is not required for hole cleaning, installation is faster and requires fewer specialized tools on the job site, keeping labor costs down.
• Built for real-world conditions - compatibility with both dry and water-saturated concrete, plus a broad substrate installation temperature range, means this epoxy adhesive performs reliably across a wide variety of field conditions without substitutions or workarounds.
• Ready-to-use out of the box - the included EMN22i mixing nozzle and nozzle extension mean you can start anchoring immediately without sourcing additional accessories separately.
• Confidence-backed code compliance - ICC-ES ESR-5334 listing under the IBC/IRC for both cracked and uncracked concrete and masonry, combined with multiple DOT listings, gives inspectors and project owners the documentation they need without extra testing or submittals.
