Adhesives Technology Ultrabond 1 Anchoring Epoxy, 22 oz Cartridge

Ultrabond 1 from Adhesives Technology is a two-component, 1:1 structural epoxy for anchoring threaded rod, bolts, and rebar in uncracked concrete. It is moisture insensitive, so it can go in and cure in damp holes, with a 40°F to 110°F application range and a 20-minute working time at 75°F. Typical work includes vertical-down and horizontal anchors, ASD tensile and shear loading, and grouting dowel bars for full-depth pavement repairs. The same epoxy is available as the 9 oz cartridge.

Frequently Asked Questions

Is Ultrabond 1 rated for cracked concrete, or uncracked only?
Ultrabond 1 is the uncracked-concrete 1:1 structural epoxy for threaded rod, bolts, and rebar dowels. When the base is cracked and the spec wants a cracked-concrete epoxy, switch to Ultrabond HS-1CC. Do not treat Ultrabond 1 as a cracked/uncracked ICC epoxy.

Can Ultrabond 1 grout pavement dowel bars and tie bars?
Yes. Ultrabond 1 is used to grout dowel bars and tie bars for full-depth concrete pavement repairs. That pavement-dowel use is a primary listing, not an afterthought on the sheet.

Does Ultrabond 1 have much odor on an occupied jobsite?
Ultrabond 1 is called out for little to no odor. That is why crews keep it on interior rod and dowel work where a strong solvent smell would shut down the floor.

Has Ultrabond 1 been NTPEP evaluated for DOT work?
Ultrabond 1 is NTPEP evaluated and carries multiple DOT listings. Confirm the current state listing before a transportation dowel job, then stay on Ultrabond 1 rather than swapping in a cracked-concrete epoxy.

Can Ultrabond 1 bond fresh concrete to hardened concrete?
Yes. Besides anchoring, Ultrabond 1 bonds fresh concrete to hardened concrete and hardened concrete to hardened concrete. Keep that bonding use in mind on a pavement or repair pour that also needs rod in uncracked concrete.

Does Ultrabond 1 hold freeze-thaw on rod and rebar?
Ultrabond 1 is used for freeze-thaw exposure on rod, bolt, and rebar work in uncracked concrete. That is a jobsite reason to keep it on exterior pavement dowels that will cycle through winter.
