About this product

An epoxy anchoring adhesive whose cure schedule runs from 40°F to 100°F. Cold concrete is the big cost: 192 hours to cure at 40°F against 24 hours at 70°F and above.

Using this specific product

Simpson Strong-Tie SET-3G High-Strength Epoxy Adhesive is listed here as the Epoxy anchoring adhesive version for anchoring adhesive, threaded rod in concrete, and rebar doweling. For bonding parts, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Epoxy anchoring adhesive; related versions can use different timing.
  • For anchoring adhesive, threaded rod in concrete, and rebar doweling, pay particular attention to surface fit, cleanliness, clamping pressure and bond-line thickness.
  • Concrete temperature of 70°F (21°C).

How to check readiness

Test a noncritical offcut or wait for the stated load milestone before stressing the joint. The cure schedule gives a gel time of 35 minutes at a concrete temperature of 70°F. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

Handling strength and full load strength are different milestones.
