Key Features

Cold-Weather Ready

This anchoring adhesive dispenses in cold, warm, and below-freezing conditions without needing to warm the cartridge first. That saves setup time when the job cannot wait for better weather.

Built for Structural Anchoring

The Simpson Strong-Tie AT-XP 30-oz. High-Strength Acrylic Anchoring Adhesive Cartridge w/ Nozzle (AT-XP30) is made for anchoring threaded rod and rebar into concrete and masonry. It is suitable for cracked and uncracked concrete plus uncracked masonry under static and seismic loading conditions.

Code-Tested Performance

Tested to ICC-ES AC308, AC58, ACI 355.4, applicable ASTM methods, and compliant with NSF/ANSI Standard 61. If you need an anchoring adhesive with documented performance, this is the kind of data you want behind it.

Overview

Simpson Strong-Tie AT-XP 30-oz. High-Strength Acrylic Anchoring Adhesive Cartridge w/ Nozzle (AT-XP30) is a two-component acrylic anchoring adhesive cartridge for setting threaded rod and rebar into concrete and masonry. This is a high-strength acrylic anchoring adhesive designed for anchoring threaded rod and rebar into concrete and masonry. Model Number: AT-XP30. It is a strong fit for contractors, concrete crews, remodelers, and serious DIY users who need a fast-curing adhesive anchor system that can keep moving in rough jobsite conditions.

What matters here is where this product works and how flexible it is on the job. AT-XP is formulated for cracked and uncracked concrete and for uncracked masonry, and it is suitable for static and seismic loading conditions. That gives you a wider range of approved anchoring applications than a general-purpose construction adhesive. If you are installing threaded rod or rebar where performance and code-backed testing matter, this is the right category of product.

Cold weather is where this acrylic anchoring adhesive really separates itself. Simpson states that it dispenses easily in cold or warm environments and even in below-freezing temperatures without needing to warm the cartridge. For anyone working outdoors, in garages, on winter retrofit jobs, or on fast-moving service work, that means less waiting around and less babysitting materials just to get a cartridge ready to run.

AT-XP is a 10:1 ratio, 30-ounce side-by-side cartridge system. That larger cartridge size makes sense for repetitive anchoring work or larger runs where you do not want to burn time changing cartridges constantly. When mixed properly, the adhesive turns teal, which gives the installer a clear visual check that the material is blended correctly before it goes into the hole.

The service-temperature range is another practical advantage. Simpson lists dry and damp in-service conditions from minus 40 degrees Fahrenheit to 180 degrees Fahrenheit, along with a substrate installation temperature range from 14 degrees Fahrenheit to 100 degrees Fahrenheit. In plain terms, this anchoring adhesive is built to cover a wide range of field conditions without forcing you into a narrow install window.

From a compliance standpoint, this product is backed by serious testing. It is tested in accordance with ICC-ES AC308 and AC58, ACI 355.4, and applicable ASTM test methods, and it is compliant with NSF/ANSI Standard 61. It is also approved for installation with a vacuum-drill bit system without further hole cleaning when used as covered in Simpson’s code report ER-263. That can help streamline installation workflow on approved jobs where dust control and hole prep efficiency matter.

Who should buy it? If you are doing structural anchoring, post-installed rebar work, threaded rod installs, or masonry anchoring where temperature swings and jobsite speed are real concerns, this is the kind of product worth paying attention to. If you just need a basic adhesive for light-duty bonding, this is more product than you need. But if you need a fast-curing concrete anchoring adhesive with tested performance and broad jobsite usability, AT-XP is built for exactly that work.

Fast Setups in Tough Weather

This concrete anchoring adhesive is built for real jobsite conditions, not perfect shop temperatures. If you are setting anchors in winter or working in changing weather, the ability to dispense without warming the cartridge first is a real time-saver.

• Dispenses in cold, warm, and below-freezing environments
• Fast cure helps when turnaround time matters

Designed for Anchoring, Not General Bonding

AT-XP is made specifically for setting threaded rod and rebar into concrete and masonry. That means the spec sheet, code testing, and load-related performance are aimed at anchor installations where failure is not an option.

• 10:1 ratio two-component acrylic anchoring adhesive
• Suitable for cracked and uncracked concrete plus uncracked masonry

Easy Visual Check During Installation

Small details matter with anchoring products. Simpson notes that properly mixed AT-XP turns teal, giving you a straightforward visual cue that the material is blended correctly before installation.
