The latest innovation from Simpson Strong-Tie, AT-XP® anchoring adhesive has been formulated for high-strength anchorage of threaded rod and rebar into concrete under a wide range of conditions. AT-XP adhesive dispenses easily in cold or warm environments with little to no odor, and when mixed properly is a teal color for easy post-installation identification.
Code-listed per IAPMO UES ER-263 in accordance with ICC-ES AC308 and IBC 2009 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)), has NSF/ Standard 61 certification (43.2 in2/1000 gal), and is made in the USA.

INSTALLATION
IMPORTANT For installation instructions, click here.
When the concrete temperature is at or below freezing, ensure any holes drilled in advance are free of frost or ice.
See below for Installation Information and Additional Data for Threaded Rod and Rebar in Normal-Weight Concrete.
SHELF LIFE
Nine months from date of manufacture in unopened cartridge.
STORAGE CONDITIONS
For best results store between 32°F–80°F (0°C– 27°C). Partially used cartridges can be stored for a limited time by leaving nozzle in place. To re-use, attach new nozzle.
COLOR
Resin — black-green, initiator — white
When properly mixed, adhesive will be a uniform teal color.
CLEAN UP
Uncured material — Wipe up with cotton cloths. If desired, approved solvents, such as ketones (MEK, acetone, etc.), lacquer thinner, or adhesive remover can be used. DO NOT USE SOLVENTS TO CLEAN ADHESIVE FROM SKIN. Take appropriate precautions when handling flammable solvents. Solvents may damage surfaces to which they are applied. Cured material — Chip or grind off surface.
GEL TIME
Under the ASTM C 881 test method, 3.5 minutes for a 60g mass at 73°F (23°C)
