Ultrabond EPX-3CC is a two-component epoxy anchoring adhesive evaluated to ACI 355.4 and ICC-ES AC308 for cracked and uncracked concrete.
Ultrabond EPX-3CC from Adhesives Technology is a two-component, 1:1 epoxy for anchoring threaded rod and rebar in cracked or uncracked concrete. It is listed to ICC-ES ESR-4533 and evaluated for dry, water-saturated, and water-filled holes, plus vertical-down, horizontal, and overhead placements, in a 48°F to 108°F application range. Other cartridge sizes are the 22oz cartridge (A22-EPX3CC) and the 53oz cartridge (A53-EPX3CC).

Is Ultrabond EPX-3CC assessed to ASTM E488 as well as ACI 355.4?
Yes. Ultrabond EPX-3CC is assessed to ACI 355.4, ICC-ES AC308, and ASTM E488 for cracked and uncracked, normal-weight and lightweight concrete, including seismic and wind loading. Design from the current EPX-3CC MPII.
Does Ultrabond EPX-3CC cover both threaded rod and rebar?
Yes. Ultrabond EPX-3CC is approved for threaded rod and reinforcing bar in cracked or uncracked concrete. Rod and rebar share the EPX listing. Internally threaded inserts are a HS-1CC extra, not an EPX extra.
How cold can Ultrabond EPX-3CC go on code-listed work versus Ultrabond HYB-2CC?
Ultrabond EPX-3CC code work starts at 48F. Ultrabond HYB-2CC installs from 23F. Stay on EPX-3CC in the 48F to 108F epoxy window. Move to HYB-2CC when the base is colder than 48F or the crew needs a 30-minute full cure at 70F.
Is Ultrabond EPX-3CC a high-strength epoxy or a hybrid?
Ultrabond EPX-3CC is a 1:1 high-performance epoxy. Ultrabond HYB-2CC is the 10:1 hybrid with a 23F install and a 30-minute full cure at 70F. Pick EPX-3CC for the ESR-4533 epoxy. Pick HYB-2CC for cold or fast-cure hybrid work.
Can Ultrabond EPX-3CC be used in water-saturated holes?
Yes. Dry, water-saturated, and water-filled holes are on the Ultrabond EPX-3CC sheet. That is wet-hole epoxy anchoring. Fully submerged underwater work stays on Ultrabond HS-1CC.
Does Ultrabond EPX-3CC contribute to LEED low-emitting credits?
Ultrabond family epoxy anchors, including EPX-3CC, are specified as low-emitting materials on ATC sheets. Confirm the current EPX-3CC environmental line if the project is chasing IEQ credit.
