AT-HP® Blue Anchoring Adhesive

AT-HP is a fast curing styrene-free methacrylate resin suitable for high performance fixing applications of threaded rod and rebar into concrete. Specially designed for structural fixings.

AT-HP Blue uses colour change technology where the adhesive changes from blue to grey when it cures, which gives a visual representation that the adhesive anchor is ready to load. Multiple cartridge sizes are available to satisfy various trades, applications, and job conditions. The coaxial 280 ml cartridge easily dispenses with a standard caulking gun, while the 380 and 825 ml dual cartridge systems utilize the DT380 and DT825 respectively.

Technical Information

Technical Data


Surfaces to receive adhesive must be clean. The base material temperature must be 0°C or above at the time of installation. For best results, material should be 20-26°C at the time of application. Cartridges should not be immersed in water to facilitate warming. To warm cold material, the cartridges should be stored in a warm, uniformly heated area or storage container for a sufficient time to allow epoxy to warm completely. Mixed material in nozzle can harden in 1-2 minutes at a temperature of 5°C or above.


Shelf Life

18 months

Storage Conditions

For best results store between 0– 26°C. Partially used cartridges can be stored for a limited time by leaving nozzle in place. To re-use, attach new nozzle.


Blue changes to grey when cured

Clean Up

Uncured material – Wipe up with cotton clothes. If desired scrub area with abrasive, water based cleaner and flush with water. If 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 can damage the surfaces to which they are applied. Cured material – chip or grind off surface
