Applications
- Threaded rod anchoring and rebar doweling into concrete and CMU
- Suitable for horizontal, vertical and overhead applications
- Multiple DOT listings
Installation
- Surfaces to receive epoxy must be clean.
- Base material temperature must be 50°F (10°C) or above at the time of installation. For best results, material should be 70°F (21°C) to 80°F (27°C) at time of application.
- To warm cold material, store cartridges in a warm, uniformly heated area or storage container. Do not immerse cartridges in water or use microwave to facilitate warming.
- Mixed material in nozzle can harden in 30 minutes at temperatures of 70°F (21°C) and above.
- Use only Simpson Strong-Tie mixing nozzles in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair ET-3G adhesive performance.
- For full instructions, see Adhesive Anchoring Installation Instructions.
Test Criteria
- ET-3G has been tested in accordance with ICC-ES AC308, AC58, ACI 355.4 and applicable ASTM test methods.
