9.6 Installation of the magnetic tape
NOTE External Magnetic Fields
The influence of the magnetic tape by magnetic fields is to be avoided!
The magnetic tape should not come into direct contact with other
magnetic fields (e.g. permanent magnets, holding magnets,
electromagnets, magnetic stands)! Irreparable damage is likely to
affect either the accuracy or even the function!
9.6.1 Processing note for the bonding
The included adhesive tapes are coated on both sides with a modified acrylic adhesive and stick well on clean,
dry and smooth surfaces. They are characterized by a high initial tack and good adhesive strength to high- and
low-energy surfaces (e.g. PE, PP), high shear and peel strength and a good humidity, UV and aging resistance.
The surface should be very clean if the surroundings are very dirty.
NOTE Surface treatment
In order to guarantee an optimal adhesion all the anti-adhesive
contaminants (e.g. oil, grease, dust, release agents, etc.) have to be
removed by a residue evaporating solvent.
Suitable for this are for example Ketones (acetone) or alcohols. Typical
solvents for cleaning are a 50/50 Isopropyl alcohol/water-mixture or
heptanes. LOCTITE or 3M offer such solvents as a substrate cleaner.
Note if dealing with solvents necessarily respond the warning of the
manufacturer!
For materials such as copper, brass, etc. the surfaces should be sealed
to prevent oxidation.
NOTE Pressure
The strength of the adhesion is directly dependent on the contact,
which the adhesive developed to the bonded surface.
Therefore, sealing with the maximum possible pressure, aids such as
pressure roller or roller are to recommend (Opt. pressure 4...5 kg/cm
adhesive surface).
NOTE Adhesive temperature
The best application (adhesive) temperature is between +18 °C and
+30 °C. Avoid colder sticking surfaces than + 10°C, because in this
case the adhesive becomes too hard and perhaps a sufficient
immediate adhesion might be difficult to achieve. After proper sticking
the stability of the connection is ensured also when the temperature is
below zero. The final adhesive power is empirical achieved after
approximately 72 hours at a temperature of + 21°C.
