Chemical Resin - Using a Nozzle

What are chemical resins?

Chemical resins are used when fastening to concrete and other such substrates, usually when a higher degree of flexibility is required. They are commonly used in conjunction with fasteners such as sleeve anchors or drop-in anchors.

The chemical is injected into the hole before the fastener is introduced. As the resin is applied under pressure it automatically finds its way into every surface of the hole. This drives all of the air from the hole, creating a high strength bond when the fastener is inserted.

Changing the resin nozzle

When using chemical resin with a new nozzle, you should ensure that you express a full nozzle’s worth of resin before you actually inject any into the hole- you will see a definite colour change as you express the old resin.

Whilst it may seem wasteful, this process ensures that the resin is mixed correctly for each application. Every time a new nozzle is attached to the cartridge this should be done.

Full application details are printed on every resin cartridge.
