- Very High Bond Conformable Acrylic Foam Tape has adhesive both sides to promote excellent adhesion to a broad range of surfaces.
- Capable of replacing rivets, spot welds, liquid adhesives, and other permanent fasteners.
- The conformable foam provides good contact, even with mismatched substrates.
- Resistance to solvents, moister and plasticiser migration.
- Provides more uniform seal on irregular surfaces.
Product Description
-------------------
VHB tapes are suitable for bonding sealed wood, many plastics,
composites and metal. Meets UL746C. After application, the bond
strength will increase as the adhesive flows onto the surface. At
room temperature, approximately 50% of the ultimate strength will
be achieved after 20 minutes, 90% after 24 hours and 100% after
. 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. 150°F [66°C] for 1
hour).
From the Manufacturer
---------------------
3M&™ VHB™ Tape 4941 is a conformable, double-sided,
pressure-sensitive, closed-cell acrylic foam tape with a paper
liner, designed to permanently adhere one material to another
while spreading the stress load across the entire length of the
joint. Once materials are joined, the tape creates a strong bond
that resists moisture, plasticizers and temperature extremes.

The Better Way to Bond
3M™ VHB™ Tape fits into grooves, around corners and through
curves while offering a durable bond. The result is an
extraordinarily strong tape that holds fast to a wide range of
materials. Applications include bonding and sealing lenses over
LED panels, bonding pre-painted metals, bonding and sealing
plastic windows to pre-painted panels. 3M™ VHB™ Tape can enhance
the appearance of finished goods by eliminating rivets and screws
while providing immediate handling strength. In most cases,
fastening with 3M™ VHB™ tape is a quicker process than drilling,
fastening, or using liquid adhesive. 3M™ VHB™ tape can be used
indoors or outdoors in a variety of applications, including
window and door assembly, sign assembly, electronics, maintenance
and dozens of other industrial applications.
Documented Reliability
3M™ VHB™ Tape 4941 provides cushioning, damping, and impact
resistance. The tape is also plasticizer resistant and carries a
UL listing, 746C. Qualification for this listing requires
high-strength retention after extended exposure to high
temperatures, humidity, cold, and cyclic conditions. The listing
below details 3M™ VHB™ Tape 4941 with the UL 746C listing, and
substrate combinations, as well as the maximum listed temperature
for each combination.
Can Tape Really Replace Mechanical Fasteners?
Yes! 3M™ VHB™ Tape is a proven alternative to screws, rivets,
welds and other forms of mechanical fasteners. Skyscrapers, cell
phones, electronic highway signs, refrigerators, marine
electronics, architectural windows, recreational vehicles and
trailers all rely on 3M™ VHB™ tape for one or more steps in the
assembly, ing, fastening, and sealing process. When joining
seams, 3M™ VHB™ tape helps create clean, smooth, water-resistant
results without rows of rivet, fastener heads, or weld seams,
which also allows for large-area graphic application with no need
for additional smoothing to accommodate fastener head
protrusions.
