EDOT Epoxy Adhesive


Formulated specifically for transportation projects, EDOT adhesive is a two-component, high-solids epoxy system. It is designed for use as a high-strength, non-shrink anchor-grouting material. EDOT adhesive provides an economical solution for transportation applications.

Key Features

  • Meets ASTM C881 and AASHTO M-235 specifications for Type I, II, IV andV, Grade 3, Class C
  • Cure times – 24 hours at 60°F, 72 hours at 40°F
  • Easy hole-cleaning procedure – no power-brushing required
  • Suitable for use in damp or wet anchor sites
  • When properly mixed, adhesive will be a uniform tan color
  • Available in 22 oz. and 56 oz. cartridges for application versatility
  • Available in 1-, 10- and 100-gallon bulk kits
  • Made in the USA using global materials



  • Threaded rod anchoring and rebar doweling into concrete and masonry
  • Multiple DOT listings

Product Includes

EDOT22-N – One EMN22i mixing nozzle and one nozzle extension are supplied with each cartridge.


Resin – white, hardener – brown. When properly mixed, EDOT adhesive will be a uniform and consistent tan color.

Storage Conditions

For best results, store between 45°F–90°F. To store partially used cartridges, leave hardened nozzle in place. To re-use, attach new nozzle.

Shelf Life

24 months from date of manufacture in unopened container.


  • Surfaces to receive epoxy must be clean.
  • Base material temperature must be 40°F or above at the time of installation.For best results, material should be 70°–80°F 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 to facilitate warming.
  • Mixed material in nozzle can harden in 30 minutes at temperatures of 70°F and above.


Use only appropriate Simpson Strong-Tie® mixing nozzle in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair epoxy performance.

Clean Up

Uncured material – Wipe up with cotton cloths. If desired, scrub area with abrasive, waterbased cleaner and flush with water. If approved, solvents such as ketones (MEK, acetone, etc.), lacquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling flammable solvents. Solvents may damage surfaces to which they are applied. Cured material – Chip or grind off surface.

Test Criteria

Anchors installed with EDOT adhesive have been tested in accordance with ASTM E1512.
