ET-HP® Epoxy Adhesive
On This Page
ET-HP is a two-component, high-solids, epoxy-based system for use as a non-shrink anchor-grouting material. ET-HP is formulated for anchoring threaded rod and rebar into concrete (cracked and uncracked) and masonry (uncracked).
- Jobsite versatility — can be specified for dry and damp conditions when in-service temperatures range from -40°F (-40°C) to 150°F (65°C)
- Permissible for use with metric threaded rod and rebar
- Multiple State and DOT approvals
- Easy hole-cleaning — no power-brushing required
- Manufactured in the USA using global materials

- Threaded rod anchoring and rebar doweling into concrete and unreinforced masonry
- Suitable for horizontal, vertical and overhead applications
- Multiple DOT listings
- 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-HP adhesive performance.
- For full instructions, see Adhesive Anchoring Installation Instructions.
- ET-HP has been tested in accordance with ICC-ES AC308, AC58, AC60, ACI 355.4 and applicable ASTM test methods.
