SET Epoxy Adhesive


On This Page

SET is a high-strength, non-shrink, epoxy-based adhesive formulated for anchoring and doweling threaded rod and rebar. Resin and hardener are dispensed and mixed simultaneously through the mixing nozzle.

Key Features

  • Code listed under the IBC/IRC for URM per ICC-ES ESR-1772
  • Meets or exceeds the requirements of ASTM C881 specification for Type I and IV, Grade 3, Class C
  • Cure times — 24 hours at 65°F (18° C), 72 hours at 40°F (4° C)
  • 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 gray color
  • Available in 22 oz. cartridge for application versatility
  • Manufactured in the USA using global materials

  • Threaded rod anchoring and rebar doweling into concrete, masonry and URM (red brick)
  • Pick-proof sealant around doors, windows and fixtures
  • Paste-over for crack injection preparation
  • Bonding hardened concrete to hardened concrete
  • CalTrans and multiple DOT listings

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 side-by-side cartridge


  • Surfaces to receive epoxy must be clean.
  • Base material temperature must be 40°F (4°C) or above at the time of installation. For best results, material should be 70°F (21°C)–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 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 SET adhesive performance.
  • For full instructions, see Adhesive Anchoring Installation Instructions.
