1. |
When using any hot melt
product, consult our
MSDS
Page
(Material Safety Data
Sheets) prior to use.
This also includes any
operating instructions
with the hot melt
application equipment or
glue gun. |
|
|
|
|
2. |
Wear proper clothing and
ALWAYS wear protective
eyewear when working
with or near hot melt
adhesives.
Heat-resistant gloves
and long sleeved shirts
should be worn. In
general, minimize any
possibility that molten
adhesive may come in
contact with unprotected
or exposed skin, hair,
or any part of the body. |

3. |
All
surfaces to be bonded
should be cleaned and
free of contaminants. If
necessary, clean or wipe
surfaces with solvent.
In some cases, lightly
abrading the surfaces
will provide best
results. |
|
|
|
|
4. |
"Open-time" varies and
can be controlled
somewhat depending on
application temperature,
amount of adhesive
applied, type of
substrate and ambient
temperature conditions.
Operator application
technique plays an
important role here in
achieving optimum
results. |
|
|
|
|
5. |
Apply the hot melt
adhesive to the more
difficult-to-bond
surface. In general,
hard, smooth surfaces
are more difficult to
bond than rough, porous
surfaces. |
|
|
|
|
6. |
Mate the surfaces to be
bonded as quickly as
possible after adhesive
has been applied for
optimum bond strength. |
|
|
|
|
7. |
Use
firmest pressure
practical for object(s)
being bonded. Do NOT
more or adjust surfaces
after contact has been
made, as inferior
bonding will result. |
|
|
|
|
8. |
Bonding some metals is
enhanced by pre-warming
the surfaces. Pre-warm
up to 200°F (95°C) for
optimum effect. |
|
|
|
|
9. |
Because of inherent
flexibility or
"rubberiness," combined
with an excellent
ability to bond to a
wide variety of
substrates, certain
stick formulas (for
example: 2124 or 6330)
can be difficult to run
in some glue guns,
especially after idle
durations greater than
20 minutes. It is
recommended to run these
flexible/rubbery
products in guns having
flexible feeding (inlet)
tubes or semi-rigid
Teflon® feeding tubes,
and to keep gun idling
times as short as
possible. |

10. |
Typically, a properly
formed hot melt adhesive
bond will achieve 50% of
its strength after one
minute, 75% of its
strength after one hour,
and 100% after one day. |
