1317 Magnet Tape
Product Data Sheet Updated : March 1996
Supersedes : September 1995
Product Description 3M Magnet Tape is a
flexible, polymer bonded
product coated on one side
with the pressure sensitive
adhesive. The magnetic
material is made using a
special process that orients
barium ferrite crystals in the
polymer binder during
manufacture. This
orientation process yields a
magnet with excellent
magnetic properties.
The high energy magnet
tape is then permanently
magnetised with multiple
north and south poles along
its length, providing a
minimum holding force of
16 ounces per square inch.
The strong holding power of
3M Magnet Tape allows its
use in relatively narrow
widths where it combines
economy with exceptional
performance capabilities.
3M Magnet Tape can be
bent, twisted and flexed
without loss of magnetic
energy. The product
conforms readily to irregular
surfaces without cracking.
It will not lose its magnetic
strength when dropped or
struck. 3M Magnet Tape is,
indeed permanently
magnetic.
3M Magnet Tape has a
high-tack pressure-sensitive
adhesive layer on one side,
protected by a peel-away
backing. The adhesive will
adhere to a wide variety of
surfaces including most
plastics, wood and metal.
The non-adhesive side may
be used to hold small
ferrous objects such as
screw drivers and other
tools. The product also
saves time by holding small
parts during assembly. 3M
Magnet Tape is a versatile
holding material, which can
be used effectively on both
metal and non-metal
surfaces.

Information Temperature Resistance
3M Magnet Tape retains
its flexibility even in cold
weather. The product
performs well indoors or
out, in hot or cold
climates. Extensive
testing in 3M laboratories
at temperatures ranging
from - 40°C to + 71°C
(- 40°F to + 160°F) has
documented the broad
range of capability of both
the adhesive and the
magnetic holding force.
Clean, Safe Handling
The magnetic side of 3M
Magnet Tape is specially
coated to ensure clean
attachment. This coating
also resists the external
physical conditions that
might otherwise result in
adhesive bonding between
magnet and application
surface. Newly painted
surfaces should be allowed
adequate drying time before
application of magnet tape.
Application
3M Magnet Tape is easily
cut with scissors or a knife.
Adhesive mounting surfaces
should be free of dirt,
grease, oil and solvent.
Following placement, the
magnet tape should be
pressed down firmly with a
roller.
Application Techniques 1. Bond strength is
dependent upon the amount
of adhesive-to-surface
contact developed. Firm
application pressure
develops better adhesive
contact & thus improves
bond strength.
2. To obtain optimum
adhesion, the bonding
surfaces must be clean dry
and well unified. A typical
surface cleaning solvent is
isopropyl alcohol & water.
Use proper safety
precautions for handling
solvents.
3. Ideal tape application
temperature range is 21°C
to 38°C (70°F to 100°F).
Initial tape application to
surfaces at temperatures
below 10°C (50°F) is not
recommended because the
adhesive becomes too firm
to adhere readily. However
once properly applied low
temperature holding is
generally satisfactory.
