ET-HP® Epoxy Adhesive

Product Details

We have discontinued our ET-HP product line and transitioned to ET-3G®. Find more information about this transition here.

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

Applications

Threaded rod anchoring and rebar doweling into concrete and unreinforced masonry
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-HP adhesive performance.
For full instructions, see Adhesive Anchoring Installation Instructions.

Test Criteria

ET-HP has been tested in accordance with ICC-ES AC308, AC58, AC60, ACI 355.4 and applicable ASTM test methods.
