NOTE: Before
processing
hot melt material,
carefully read
the
material
manufacturer's
Material
Safety Data
Sheet
(MSDS)
or material
information
sheet. Nordson
supplies only
general processing
instructions
and is
not liable for hazards
associated
with or damage
caused by the
use
of hot melt material.
Store
the
material in
dry areas
at
room
temperature. Keep it in covered,
dust-protected
containers.
Keep the substrate
at room
temperature, dry
and free of dust and
grease.
Perform
tests to
determine the
suitable hot melt material,
optimum
operating conditions,
and
preliminary
treatment
of the
substrate
for
the application.
Some substrates
contain
plasticizers
and
other ingredients which
dissipate over
time. ln some
cases, surfaces
are treated with waxes,
anti-stick
oils, etc.
Without
adequate
pretreatment,
the hot melt bond in
these
applications
may be defective
at the time
of dispensing.
The
application
temperature
of the hot melt
material at the nozzle is
crucial for effective
bonds.
Refer to the
material manufacturer's
MSDS
or material information
sheet.
Avoid unnecessary
thermal
stress. lf the
work is interrupted, reduce
the
melting
temperature.
Avoid
heating the hot
melt material
above the
prescribed
processing
temperature. Higher
temperatures
may cause
charring of the hot melt
material.
This results
in downtime. ln
addition, material
may
generate
dangerous vapors
at excessively
high temperatures.
Remove these
vapors
by using
appropriate
exhaust
systems.
