Ultrabond 1300 is a non-sag, high-modulus epoxy for setting threaded rod and rebar dowels in uncracked concrete, the same chemistry used in bulk pumps.
ULTRABOND 1300 is a two-component, 1:1 non-sag epoxy for anchoring and doweling threaded rod and rebar in uncracked concrete. It is moisture insensitive in damp holes, non-abrasive in bulk pumps, and places from 40°F to 110°F. Typical work includes pavement dowel and tie bars, raised markers, and bonding fresh or hardened concrete. Working time is about 16 minutes at 75°F, with a 24-hour full cure. Also available as the 9 oz cartridge, the 1 gallon kit, and the 2 gallon kit.

Can an NS cartridge of Ultrabond 1300 handle pavement-dowel work that usually runs in a bulk pump?
Yes. NS Ultrabond 1300 is the same uncracked, non-sag, high-modulus epoxy that bulk pumps place. The cartridge is how a crew sets dowels, rod, or markers without a pump. Cracked-concrete work still belongs on HS-1CC or EPX-3CC.
Can cartridge Ultrabond 1300 bond raised pavement markers?
Yes. Bonding raised pavement markers to concrete or asphalt is a listed Ultrabond 1300 use. The cartridge is how a striping or marker crew carries that same non-sag epoxy without a bulk pump.
Does cartridge Ultrabond 1300 stay non-sag in a vertical-down dowel hole?
Yes. Ultrabond 1300 is a non-sag high-modulus epoxy. Vertical-down and horizontal pavement-dowel work is why the NS cartridge exists. It is still uncracked-only.
Does cartridge Ultrabond 1300 have much odor on a night shift?
Ultrabond 1300 is called out for little or no odor. Moisture-insensitive chemistry plus low odor is why the NS cartridge is used on occupied or night-work pavement repairs.
What placement temperature does cartridge Ultrabond 1300 list?
Cartridge Ultrabond 1300 places between 40F and 110F, same as bulk 1300. Keep the cartridge in that band so the non-sag epoxy still moves on a pavement-dowel or marker job.
Is cartridge Ultrabond 1300 used under allowable stress design?
Yes. Ultrabond 1300 covers short-term tensile anchoring and shear loading under allowable stress design in uncracked concrete. It is not a cracked-concrete ICC adhesive.
