SET-XP is an epoxy-based high-strength anchoring adhesive. SET-XP is a 1:1 ratio, two-component anchoring adhesive for anchoring and doweling into concrete (cracked and uncracked) and masonry (uncracked) applications.

Key Features

  • Design flexibility — permitted for sustained load performance at elevated temperature.
  • 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).
  • Recognized per AC308 to be used for rebar development and splice length design provisions of ACI 318.
  • Approved for installation with vacuum-drill bit system without further hole cleaning. See Code Report (ESR-2508) for approved system.
  • Easy hole-cleaning — no power-brushing required.
  • Manufactured in the USA using global materials.

  • Threaded rod anchoring and rebar doweling into concrete and masonry
  • Recognized per AC308 to be used for rebar development and splice length design provisions of ACI 318
  • 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 between 70°F (21°C) and 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 appropriate Simpson Strong-Tie mixing nozzle in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair SET-XP adhesive performance.
  • For full instructions, see Adhesive Anchoring Installation Instructions.

Test Criteria

  • SET-XP has been tested in accordance with ICC-ES AC308, AC58, ACI 355.4 and applicable ASTM test methods.
