Technical Bulletin
Summary
August, 2018
This bulletin addresses the long-term durability of 3M™ VHB™ Tapes and
their ability to perform in certain types of demanding environments. This
will be addressed from a variety of view-points including chemical
composition, resistance to harsh environments, 3M and independent tests
for product durability, and certain applications where 3M™ VHB™ Tape
products have demonstrated excellent ability to perform in demanding
applications. Test results on moisture resistance, UL durability,
accelerated weathering, outdoor weathering, thermal cycling and fatigue
resistance will be discussed.
3M is a technological leader in acrylate pressure sensitive adhesive (PSA)
technology. 3M™ VHB™ Tapes represent examples of 3M’s proprietary,
state-of-the-art chemistry. The long-term aging resistance lies in the
polymer comprising 3M™ VHB™ Tapes. The chemical bonds that make up
the polymer chains consist of carbon-carbon single bonds that are highly
resistant to energy in the form of heat or ultraviolet light, as well as
chemical attack. In less durable foams or adhesives, such conditions could
lead to cleaving of the polymer backbone and thus a weakening of
mechanical properties. In the case of acrylic adhesives and foams,
however, additional crosslinking is chemically favored over chain scission
(cleavage). This means that, rather than undergoing a process of
decomposition, the acrylate materials will tend to build modulus very
slightly over extended exposures. This translates to a stronger, long lasting
bond.
Temperature Exposure
Because of the demanding and diverse applications users have for
3M™ VHB™ Tapes, durability has always been a key interest in the
performance of these products. One of the first issues for tapes is
retention of tack and adhesion after exposure to elevated
temperatures. Bonds made with 3M™ VHB™ Tapes can tolerate
periodic, short- term exposures to temperatures up to 300°F (150°C)
for most Foam Tapes.
