3M VHB Tape Durability

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.
