Adhesive Anchoring Solutions

Hilti offers injectable chemical anchors in the popular epoxy resin formulations as well as newer hybrid adhesives that offer both design and installation flexibility. Epoxy and hybrid adhesives are traditionally allowed to be spaced closer together and closer to the edge-of-slab compared to their mechanical anchor counterparts. After the chemical component has cured, Hilti adhesive anchors boast some of the highest load capacities in the industry for chemical or mechanical anchors.

Why choose adhesive anchors on your project?

Both resin epoxy adhesive anchors and hybrid adhesive anchors have performance advantages in different installation conditions. Epoxy anchors are traditionally slower curing formulations while hybrid adhesives tend to have less gel time and cure much faster than epoxies. Under certain conditions, hybrid adhesives can improve productivity on a jobsite by allowing workers to install and load the anchors on the same day. However, for installations requiring deep embedments a slower curing epoxy is ideal as the time needed to dispense the adhesive and insert the threaded rod or rebar can exceed the gel time of a hybrid adhesive. 

Additionally, epoxies and hybrid adhesives are affected by ambient temperatures and the temperature of the base material at the time of installation. If your project is being constructed in a particularly warm weather environment, epoxy anchors may be the best choice as their slower gel and cure times may give installers additional working time to ensure that the bars are fully inserted to the proper embedment depth and are perpendicular to the surface. For particularly cold weather environments, hybrid adhesives may be the best choice as their faster gel and cure times could optimize installers’ time on the jobsite by reducing the amount of time between installing an anchor and loading that same anchor compared to the same process using epoxies. In summary, there are advantages and disadvantages to each adhesive anchor type and knowing when to use which adhesive will allow you to optimize your project and your jobsite.
