2. Other adhesive fixings
• Polyurethane adhesives
• Epoxies
• Silicone sealants

Structural adhesives like 3M DP410 provide very high bond
strength and resistance against mechanical stress. When
tag is attached with sealant adhesive, insert a layer of
sealant under the tag and press the tag on the surface.
Increase the bond by adding extra sealant from the tag
holes. Adhesive type and thickness may have an effect on
tag performance. In general more than 2mm layer of
adhesive under the tag should be avoided. Please refer to
adhesive supplier for exact fixing instructions and test the
performance with chosen adhesive.

3. Mechanical fixing
Mechanical fixing is
recommended to be used in
every application that includes
risk for high mechanical stress
or low temperature during tag
fixing. During fixing make sure
there is no air gap left in
between the metal surface and tag. Hole dimensions are
identical with and without compression limiters. DIN 7985
M4 screws can be used as a reference.

To achieve the optimal performance locate the tag on
metal in a way that there is metal on both ends of the tag,
like shown below. Ideally the tag is placed on large even
metal surface with direct metal contact underneath the
whole tag. Tag polarization is along the longest dimension.
