3M™ VHB™ Tapes provide the convenience and simplicity of a tape fastener and are ideal for use in many interior and exterior bonding
applications. In many situations, they can replace rivets, spot welds, liquid adhesives and other permanent fasteners.
These 3M™ VHB™ Tapes are made with acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing and stress
relaxing properties which provides these tapes with their unique characteristics. The acrylic chemistry provides outstanding durability
performance.
These tapes utilize a variety of specific foam, adhesive, color and release liner types to provide each product/family with specific features.
These features can include adhesion to specific or a broad range of materials, conformability, high tensile strength, high shear and peel
adhesion, resistance to plasticizer migration, and UL746C recognition. All 3M™ VHB™ Tapes have excellent
durability and excellent solvent and moisture resistance.
The tapes included in this data page have unique performance features that are not typically required in most common applications.
Please refer to “3M™ VHB™ Tapes” technical data sheet for applications that do not require the special features incorporated in these
specialty tapes.

Slitting Tolerance
Standard slitting tolerance ± 1/32 inch (± 0.031 inch, ± 0.79 mm).
Precision slitting with slitting tolerance of ± 1/64 inch (± 0.016 in., ± 0.41 mm) is available on select products with minimum
order of full web increments.
Core Size
All products are provided on a 3 inch ID Core (76.2 mm)
Converted Parts
In addition to standard and custom roll sizes available from 3M through the distribution network, 3M™ VHB™ Tapes are also
available in limitless shapes and sizes through the 3M Converter network. For additional information, contact 3M Converter
Markets at 1-800-223-7427 or on the web at www.3M.com/converter.
Shelf Life
All 3M™ VHB™ Tapes have a shelf life of 24 months from date of manufacture when stored at 40°F to 100°F (4°C to 38°C)
and 0-95% relative humidity. The optimum storage conditions are 72°F (22°C) and 50% relative humidity.
Performance of tapes is not projected to change even after shelf life expires; however, 3M does suggest that 3M™ VHB™
Tapes are used prior to the shelf life date whenever possible.
The manufacturing date is available on all 3M™ VHB™ Tape cores as the lot number. The lot number, typically a 4 digit code,
is a Julian date (Y D D D). The first digit refers to the year of manufacture, the last 3 digits refer to the days after January 1.
Example: A lot number of 9266 would translate to a date of manufacture of Sept. 22 (266th day of year) in 2009. On most
products this is found as the 4 digits after the “9” following the product number. For tapes printed continuously around the
core (e.g. 3M™ VHB™ Tape 5952 family) the lot number typically will be the string of 4 digits preceding the product number.
Special Cases:
Plasticized Vinyl – Plasticizers compounded in soft vinyl can migrate into adhesives and significantly change their performance
characteristics. 3M™ VHB™ Tapes 4945 family has very good plasticizer resistance and adhesion to many vinyl formulations.
Because of the wide variation in vinyl formulations, however, evaluation by the user must be conducted with the specific vinyl
used to ensure that performance will be satisfactory over time. Problems related to plasticizer migration can often be predicted
by accelerated aging of assembled parts at 150°F (66°C) for one week).
