EDOT adhesive is formulated to provide an economical and high-strength solution for transportation projects.* It is a two component, high-solids epoxy-based system that is a non-shrink anchor grouting material. Resin and hardener are dispensed and mixed simultaneously through the static mixing nozzle. EDOT meets the requirements of ASTM C-881 and AASHTO M235 specifications for Type I, II, IV and V, Grade 3, Class C.

Surfaces to receive epoxy must be clean. The base material temperature must be 40ºF or above at the time of installation. For best results, material should be 70ºF–80ºF at the time of application. Cartridges should not be immersed in water to facilitate warming. To warm cold material, the cartridges should be stored in warm, uniformly heated area or storage container for a sufficient time to allow epoxy to warm completely. Mixed material in nozzle can harden in 5-7 minutes at a temperature of 40ºF or above.

Anchors installed with EDOT adhesive have been tested in accordance with ASTM E488 and ASTM E1512.
|Consistency (77ºF)||ASTM C-881||Non-sag/ thixotropic paste|
|Heat deflection||ASTM D-648||129ºF (54ºC)|
|Bond strength (moist cure)||ASTM C-882||3054 psi (2 days) 3425 psi (14 days)|
|Water absorption||ASTM D-570||0.04% (24 hours)|
|Compressive yield strength||ASTM D-695||10,053 psi (7 days)|
|Compressive modulus||ASTM D-695||393,000 psi (7 days)|
|Gel time||ASTM C-881||46 min. @ 73 ºF (23ºC) 32 min. @ 90 ºF (32ºC)|
For best results, store between 45ºF–90ºF. To store partially used cartridges, leave hardened nozzle in place. To re-use, attach new nozzle.
Very good to excellent against distilled water, dilute inorganic acids and alkalis. Fair to good against organic acids and alkalis, and many organic solvents. Poor against ketones. For more detailed information, see Technical Bulletin T-SAS-CHEMRES or contact Simpson Strong-Tie.

24 months from date of manufacture in unopened container.
Resin – white, hardener – brown When properly mixed, EDOT adhesive will be a uniform and consistent tan color.
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.
