Preparation
of the surfaces and application techniques
To achieve the highest bonding
strength they must be clean, dry and smooth. Use
solvents, as a mix of isopropyl alcohol and water
or heptane to clean surfaces. When using solvents,
please read the use instructions and the warnings
of the manufacturer. (Phases A & B)
Setting depends on the level
of bond-surface contact.With a strong pressure
a better bonding contact is achieved and that
improves setting. (Phases C & D)
After application, setting increases
as much as the bond is penetrated into the “surface
unevenness”.At room temperature, about 50%
of the final setting can be achieved after 20
minutes, 90% after 24 hours and 100% after 72
hours. In some case setting can be helped with
heat (for example, 70° for 1 hour). In this
way surfaces achieve a better level of wet resistance.

1) Notes:
- The ideal temperature for the application of the
tape goes from 21°C to 38°C. Application
min. temperature:
| Temperature |
Products |
| 10°C |
9460, 9469, 9473, 4611, 4613, 4646, 4655,
4905, 4910, 4915, 4918, 5965, 5970, 5975 |
| 15°C |
4936, 4941, 4956, 4991 |
| 0°C |
4943, 4957 |
Please do not apply the tape with initial temperatures
lower than the min. values suggested, as the bond
becomes to stiff and cannot adhere. Once applied
the tape in the right way, the use at low temperatures
is generally satisfying. To correctly apply 4943
and 4957 tapes, please check that the surfaces are
dry and free from condensation due to moisture.
2) - Some support must be prepared before fixing.
a. most porous materials (ex. concrete) or
fibrous (ex. wood) must be sealed to achieve an
even surface.
b. Some materials (for example, copper,
brass, plasticized vinyl) must be prepared to prevent
from the interaction between bond and support.
c. Fixing on glass in highly humid environment
must be made after an appropriate preparation of
the surface to ensure long life.
General information
The user should assess the types of applications
on surfaces, solvents, paints, seals etc. chosen
in the true use conditions, as well as the tape
and the specific support. If bond is not suitable
for the application, please contact 3M Bonding Technology
Department to achieve information on alternative
products.
For further information, please read attentively
the technical sheet of the product.
