Product Description
VHB Joining Systems utilise
firm acrylic adhesives which
have excellent long term
holding power. The peel
adhesion and tensile
holding power
of products in the VHB
family are significantly
higher then typical pressure
sensitive tape products.
Resistance to solvents,
temperature extremes, and
U. V. Light make VHB
products suitable for many
interior and exterior
applications.

Information
Bond strength is dependent
upon the amount of
adhesive -to-surface contact
developed. Firm application
pressure develops better
adhesive contact and thus
improving bond strength.
To obtain optimum
adhesion, the bonding
surfaces must be clean, dry
and well unified. Typical
surface cleaning solvents
are isopropyl alcohol/water
mixture (rubbing alcohol) or
heptane. Use proper safety
precautions for handling
solvents.
It may be necessary to seal
or prime some substrates
prior to bonding.
a. Most porous or fibred
materials (e.g. wood) will
require sealing to provide a
unified surface.
b. Some materials (e.g.
copper, brass, plasticised
vinyl) will require priming or
coating to prevent
interaction between
adhesive and substrates.
Ideal tape application
temperature range is 20 to
40°C. Initial tape
application to surfaces at
temperatures below 15°C is
not recommended because
the adhesive becomes too
firm to adhere readily.
However, once properly
applied, low temperature
holding is generally
satisfactory.
In some cases bond
strength can be increased
and ultimate bond strength
can be achieved more
quickly by exposure of the
bond to elevated
temperatures (e.g. 65°C) for
one hour. This provides
better adhesive wetout on to
the substrates.
CAUTION
The following situations
must be evaluated
thoroughly to determine
whether VHB products are
suitable for the intended
use.
Applications of 4952 which
require performance at
severe cold temperatures
must be thoroughly
evaluated, if the expected
use will subject the VHB
Joining System fastener to
high impact stresses. For
cold temperature
applications from 0 to 15°C
use 4951 (see VHB Special
Feature products data
sheet).
Applications
4932 and 4952 have a
specially formulated
adhesive for attachment to
low surface energy
substrates e.g. Polyethylene
and polypropylene.
As with all VHB Tape
systems thorough
evaluation should take
place prior to final adhesive
selection.
