About this product

A hybrid acrylic anchoring adhesive built for speed and cold: its schedule starts at 23°F, where the gel time is 50 minutes and the cure time 5 hours, against 3 minutes and 30 minutes at 68°F.

Using this specific product

Simpson Strong-Tie AT-3G High-Strength Hybrid Acrylic Adhesive is listed here as the Acrylic 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 Acrylic 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.
  • Base material temperature of 68°F (20°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 3 minutes at a base material temperature of 68°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.
