unauthorized attempt be made to remove a tag from its asset. Do not glue the magnet to the back of
the tag; this will prevent the anti-tamper feature from working.
4.2.4 Final steps
Remove the other cover from the gel pad and position the tag in a suitable location on the asset.
Press firmly and ensure no air bubbles remain visible.
The gel pad will take up to 24 hours to cure to full bond strength.
If fitting the tag to the asset using screws or rivets with the VHB gel pad it is helpful to first attach the
tag to the asset using the gel pad and then to drill the required holes for the screws or rivets as the
tag will be held in the correct location by the VHB pad while you are working.
If fitting the tag to the asset using screws or rivets without the VHB gel pad, mark the centre of each
hole using the tag’s fixing holes as your guide.
Then to drill the required holes for the screws or rivets and fix the tag to the asset using the screws
or rivets.
4.3 Removing the TGM
The tag may require removal from the object either at the end of its functional life, or in instances where the
tag has been damaged, or where the asset is at end of its life cycle and must be replaced or disposed of. In
the case of asset replacement or disposal and where the tag is still fully functional, the tag can be installed
onto a new asset with a new gel pad.
4.3.1 Requirements
1 thin, flat instrument or blade, such as a dinner table knife
4.3.2 Removal
For plastic assets or assets made of softer metal, it is highly likely that some surface damage could
occur during removal of the tag. Take as much care as possible to avoid this by working carefully to
break the VHB bond and use an instrument that is less likely to gouge or scratch the asset surface.
Carefully insert the blade into the gel pad repeatedly, working all the way around the edge of the tag.
Repeat this as many times as it take to loosen enough of the gel pad around the edge of the tag to
allow gentle twisting or rotation of the tag in a clock-wise then anti-clockwise manner. Use the blade
to continue loosening or breaking up the gel pad to allow greater rotation of the tag.
Continue to twist the tag until it comes off the object.
Notes:
The anti-tamper feature (if used) will cause the tag to alarm immediately if any attempt is made to remove the
tag before the end of its functional lifespan.
Do not try to pull the tag off the object when removing it, the best way to break down the bond between the
gel pad and the tag & object is to rotate the tag clockwise and anti-clockwise repeatedly.
