AT-XP® FAST-CURING ANCHOR ADHESIVE FOR CRACKED AND UNCRACKED CONCRETE

AUTHORIZED SIMPSON STRONG-TIE DISTRIBUTOR

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.

FEATURES:
  • AT-XP adhesive has passed the demanding adverse condition tests of ICC-ES AC308 pertaining to reduced temperature, elevated temperature and long-term creep
  • Code-listed per IAPMO UES ER-263
  • Can be used under static and seismic loading conditions in both cracked and uncracked concrete
  • Low-odor formula dispenses easily at below-freezing temperatures without the need to warm cartridge
  • Cures in substrate temperatures as low as 14°F in 24 hours or less
  • Easiest hole-cleaning method – no power brushing needed
  • When properly mixed, adhesive will be a teal color for easy identification
  • Available in 9.4 oz., 12.5 oz. and 30 oz. cartridges for jobsite versatility
APPLICATIONS:
  • Threaded rod anchoring into concrete
  • Rebar doweling into concrete
  • Suitable for horizontal, vertical and overhead applications

    1. Cartridge estimator is available above.
    2. Detailed information on dispensing tools, mixing nozzles and other adhesive accessories is available under the “Accessories” tab.
    3. Use only Simpson Strong-Tie® mixing nozzle in accordance with Simpson Strong-Tie instructions. Modification or improper use of mixing nozzle may impair AT-XP adhesive performance.
    4. One AMN19Q nozzle and one nozzle extension is supplied with each cartridge.
    CURE SCHEDULE:

    AT-XP Cure Schedule

    For water-saturated concrete (including damp or water-filled holes), the cure times must be doubled. Gel Time under the ASTM C 881 test method, 3.5 minutes for a 60g mass at 73°F (23°C)

    CHEMICAL RESISTANCE:

    Very good to excellent against distilled water and inorganic acids. Fair to good against organic acids and alkalis, inorganic alkalis and many organic solvents. Poor against ketones.

    STORAGE:

    For best results store between 32°F–80°F (0°C– 27°C). Product shelf life is nine months from date of manufacture in unopened cartridge. 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.

      AT-XP Fast Curing Anchor Adhesive Allowable Loads

      AT-XP® anchoring adhesive has been tested per ICC-ES Acceptance Criteria AC308 to determine the strength design values, and is codelisted
      per IAPMO UES ER-263. In some cases, the designer may prefer to work with allowable loads. AC308 provides a method for converting
      strength design values to allowable loads. The table above presents allowable load values using the AC308 procedure for the specific conditions
      described in the footnotes.

  • When the concrete temperature is at or below freezing, ensure any holes drilled in advance are free of frost or ice.

    HOLE PREPARATION: Horizontal, Vertical, and Overhead Applications

    1. Drill hole to specified diameter and depth.

    2 - Blow

    2. Remove dust from hole with oil-free compressed air for a minimum of 4 seconds. Compressed air nozzle must reach the bottom of the hole.

    3 - Brush

    3. Clean with a nylon brush for a minimum of 4 cycles. Brush should provide resistance to insertion. If no resistance is felt, the brush is worn and must be replaced.

    4 - Blow

    4. Remove dust from hole with oil-free compressed air for a minimum of 4 seconds. Compressed air nozzle must reach the bottom of the hole.

    CARTRIDGE PREPARATION:

    1. Check expiration date on product label. Do not use expired product.Product is usable until end of printed expiration month.

    2. Open cartridge per package instructions.

    Attach

    3. Attach proper Simpson Strong-Tie® nozzle to cartridge. Do not modify nozzle.

    4 - Blow

    4. Insert cartridge into dispensing tool.

    4 - Blow

    5. Dispense adhesive to the side until properly mixed (uniform color).

    FILLING THE HOLE:
    • VERTICAL

      DRY AND DAMP HOLES:

      Fill

      1. Fill hole 1/2 – 2/3 full, starting from bottom of hole to prevent air pockets. Withdraw nozzle as hole fills up.

      Insert

      2. Insert clean, oil free anchor (threaded rod or rebar), turning slowly until the anchor contacts the bottom of the hole.

      Do not disturb

      WATER FILLED HOLES:

      Fill

      1. Fill hole completely full, starting from bottom of hole to prevent water pockets. Withdraw nozzle as hole fills up.

      Insert

      2. Insert clean, oil-free anchor (threaded rod or rebar), turning slowly until the anchor contacts the bottom of the hole.

      Do not disturb

      3. Do not disturb anchor until fully cured. (See cure schedule for specific adhesive.)

    • HORIZONTAL AND OVERHEAD

      Install

      1. Install Simpson Strong-Tie® ARC adhesive retaining cap. Refer to Adhesive Retaning Caps for proper ARC size.

      Fill

      2. Fill hole 1/2 – 2/3 full, starting from bottom of hole to prevent air pockets. Withdraw nozzle as hole fills up.

      Insert

      3. Insert clean, oil-free anchor (threaded rod or rebar), turning slowly until the anchor contacts the bottom of the hole.

      Do Not Disturb

      4. Do not disturb anchor until fully cured. (See cure schedule for specific adhesive.)

    • ANCHORING WITH SCREENS

      Fill

      1. Fill screen completely. Fill from the bottom of the screen and withdraw the nozzle as the screen fills to prevent air pockets. (Opti-Mesh® screens: Close integral cap after filling.)

      Insert

      2. Insert adhesive filled screen into hole.

      Insert

      3. Insert clean, oil free anchor (threaded rod or rebar), turning slowly until the anchor contacts the bottom of the screen.

      Do Not Disturb

      4. Do not disturb anchor until fully cured. (See cure schedule for specific adhesive.)
