URS: Anchorage – Adhesives

SET-XP® and SET® High-Strength Structural Anchoring Adhesives

SET-XP® is a two-component, 1:1 ratio, high-solids, epoxy-based anchoring adhesive formulated for optimum performance in both cracked and uncracked concrete. SET-XP® adhesive has been rigorously tested in accordance with ICC-ES AC308, ACC355.4 and 2012 IBC requirements and has proven to offer increased reliability in the most adverse conditions, including performance in cracked concrete under static and seismic loading.

SET® is a two-component, 1:1 ratio, high-solids, epoxy-based adhesive for use as a high-strength, non-shrink anchor-grouting material. Resin and hardener are mixed and dispensed simultaneously through the mixing nozzle. SET meets or exceeds the requirements of ASTM C-881 specification for Type I, II, IV and V, Grade 3, Class B and C. Both SET and SET-XP are made in the U.S.A.

AT-XP® and AT Fast-Curing Anchoring Adhesives

AT-XP® anchoring adhesive from Simpson Strong-Tie has been formulated for high-strength anchorage of threaded rod and rebar into concrete under a wide range of conditions, such as cold weather installations. Code-listed per IAPMO UES ER-263 in accordance with ICC-ES AC308, ACC355.4 and IBC 2012 requirements for cracked and uncracked concrete in static or seismic conditions, AT-XP anchoring adhesive has demonstrated superior performance in reduced-temperature testing (14°F (-10°C)).

AT is a two-component, high-solids, 10:1 ratio, acrylic-based adhesive for use as a high-strength, anchor-grouting material. Formulated for use in all types of weather, AT is designed to dispense easily and cure at temperatures down to 0°F. AT and AT-XP are both made in the U.S.A.
