Gerber 3M™ Adhesive Transfer Tape 468MP
Adhesive Transfer Tape 468MP 12” wide 60 yards P83177A
These adhesives complement our LexEdge and Static Cling applications. The laminating adhesives provide the finish step in the production of decals.
3M 468MP Adhesive Transfer Tape is for long-term bonding of graphic nameplates, overlays (i.e. subsurface printed Lexan), rating plates, membrane switches, etc. to metal and high surface energy plastics in the aerospace, medical and industrial equipment, automotive, appliance and electronic markets. When bonding a thin, smooth, flexible material to a smooth surface, use 467MP with a 2.3 mil adhesive; use 468MP, with 5.2 mil of adhesive, when a texture is visible on one or both surfaces.
DESCRIPTION
Adhesive Transfer Tape 467MP and 468MP are popular choices for graphic attachment and
membrane switch applications because they have excellent quality, consistency and durability.
These products offer the following excellent performance characteristics: Clarity (virtually free of
vapor inclusions that are commonly found in adhesives produced by the traditional solvent
coating technique); Excellent high temperature performance as well as excellent shear strength
(that minimizes edge lifting and slippage of parts); Excellent resistance to harsh environments:
the adhesive can withstand splashes of organic solvents, weak acids and bases and salt water,
cleaning solutions, germicidals, disinfectants, oils, etc.
In addition, these perform well after exposure to humidity and hot/cold cycles and provides
some initial repositionability when bonding to plastic parts (not metal) which allows graphic parts
to be lifted and repositioned if initial alignment is incorrect.
INTENDED APPLICATIONS
Application to high surface energy substrates (HSE). On an HSE substrate, adhesive spreads
out to “wet” the surface to be bonded. The higher the surface energy, the better the bond
performance. Most popular applications are for appliance, transportation and automotive,
electronics and general industrial for name plates, graphic overlaps:
Long term bonding of graphic nameplates and overlays (“subsurface” printed
polycarbonate or polyester) to metal and high surface energy plastics in the aerospace,
medical and industrial equipment, automotive, appliance and electronic markets.
Bonding metal nameplates and rating plates in the aerospace, medical and industrial
equipment, automotive, appliance and electronic markets.
Bonding graphic overlays for membrane switches and for bonding the complete switch to
the equipment surface.

High speed processing of parts in the medical, telecommunications and electronics
markets (medical components, durable labels, flexible circuits).
Lamination to industrial foams for rotary die-cutting of small gaskets for industrial and
electronics markets.
APPLICATION TECHNIQUES
For maximum bond strength (during installation of the final part) the surface should be
thoroughly cleaned and dried. Typical cleaning solvents are heptane* (for oily surfaces) or
isopropyl alcohol for plastics. Use reagent grade solvents since common household materials
like rubbing alcohol frequently contain oils to minimize the drying affect on skin and can interfere
with the performance of a pressure-sensitive adhesive.
Note: Carefully read and follow the manufacturer’s precautions and directions for use when
working with solvents. These cleaning recommendations may not be in compliance with the
rules of certain air quality management districts in California; consult applicable rules
before use.
It is necessary to provide pressure during lamination (1.5-20 pli recommended) and during final
part installation (10-15 psi) to allow the adhesive to come into direct contact with the substrate.
Using a hard edged plastic tool, which is the full width of the laminated part, helps to provide the
necessary pressure at the point of lamination. Heat can increase bond strength when bonding to
metal parts (generally this same increase is observed at room temperature over longer times,
weeks). For plastic parts, the bond strength is not enhanced with the addition of heat.
The ideal adhesive application temperature range is 60°F (15.6°C) to 100°F (38°C). Application
is not recommended if the surface temperature is below 50°F (10°C) because the adhesive
becomes too firm to adhere readily. Once properly applied, at the recommended application
temperature, low temperature holding is generally satisfactory.
When bonding a thin, smooth, flexible material to a smooth surface, it is generally acceptable to
use 3M 467MP. If a texture is visible on one or both surfaces, the 3M 468MP would be
suggested. If both materials are rigid, it may be necessary to use a thicker adhesive to
successfully bond the components.

IV. Low Temperature Performance
The glass transition temperature for 467MP and 468MP is -31°F (-35°C). Many applications
survive below this temperature (factors affecting successful applications include: materials
being bonded, dwell at RT before cold exposure and stress below the TG [i.e. expansion/
contraction stresses, impact]). Optimum conditions are: bonding high surface energy

materials, longer time at RT before cold exposure and little or no stress below the Tg. The
lowest service temperature is -40°F (-40°C).
Note: 467MP and 468MP are not recommended for low energy plastics (polypropylene,
polyethylene, powder coated paints).
