Hot Melt Adhesives offer many benefits for success with a variety of
assembly and/or closure applications.
Open time or bonding range is the maximum time
between applying adhesive and joining the surfaces.
With 3M
™
Hot Melt Adhesives you have wide latitude
in bonding range selection to meet
your process needs.
Move assemblies immediately and eliminate clamps,
fixturing and drying time and energy. Each adhesive
is engineered for efficient application with an
easy-to-use 3M portable applicator.
Minimal operator training.

Hot Melt Adhesives
are applied as a molten liquid,
so they quickly fill gaps and
wet the entire bonding surfaces.
As a result, they often exceed
100 psi shear strength, quickly
giving your application fast,
convenient strength. Select
from many options to fit
your specific application —
including peel resistant
or highly heat resistant
options.

Variety
of
Surfaces
Unlike mechanical fasteners
and sealing tapes, hot melt
adhesive is virtually invisible
between the mating surfaces.
Since hot melts are dispensed as
liquids, it is easy to apply exactly
where adhesive is needed.
You can combine a wide
variety of materials ranging
from wood to corrugated
cardboard, heat-sensitive
foam and even plastics and
metals. For heat sensitive
materials, low melt adhesives
are dispensed at lower
temperatures.

Selector Guide
Step 1: Select your assembly type
Small Joint Assembly
Small joints are typically irregularly
shaped, but only a few inches of
overlap area.
Large Surface Lamination
Two surfaces of similar size, either
rigid or flexible, are bonded or
laminated together where majority of
the surface is covered by adhesive.
Mounting and Trim Attachment
Small objects are mounted or added
to a large surface.
Sealing, Potting and Encapsulating
Adhesive flows over and around
a component or fills a chamber to
protect and seal components therein.
Step 2: After selecting your assembly, choose the substrate and identify
the adhesive that performs best for your application.

Hot Melt Adhesive is dispensed at 350–385°F. Low Melt Adhesive is dispensed at 250–270°F.
NOTE:
Low Melt (LM) adhesives liquefy at lower operating temperatures for bonding heat
sensitive surfaces such as bead board and foams.
NOTE:
High Temperature (HT) has high temperature resistance.
