VHB™ Tapes
Technical Data
June, 2011
Product Description:
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.
Note: All 3M™ VHB™ Tapes should be thoroughly evaluated by the end user under actual use conditions with intended
substrates to determine whether a specific tape is fit for a particular purpose and suitable for user’s method of application,
especially if expected use involves extreme environmental conditions or high dead load stress.

3M™ VHB™ Tapes Adhesive Types:
Multi-Purpose Acrylic: This adhesive bonds to a wide range of materials including metals, glass, and high and medium surface
energy plastics and paints. This unique adhesive also has the ability to resist migration of plasticizers in vinyl substrates.
Modified Acrylic: This adhesive bonds to medium low surface energy paints and plastics, including many powder coated
paints in addition to the substrates listed with the multi-purpose acrylic adhesive (except plasticized vinyl).
General Purpose Acrylic: This adhesive bonds to most higher surface energy substrates including metal, glass and high
surface energy plastics.
Low Temperature Appliable Acrylic: This adhesive can make bonds down to 32°F (0°C), compared to 50°F (10°C) for most
acrylic adhesives. This adhesive system bonds to most high surface energy substrates including metal, glass and high surface
energy plastics.
Low Surface Energy: This high performance synthetic adhesive bonds to many lower surface energy substrates, including
many plastics and power coated paints, plus smooth general purpose substrates.
3M™ VHB™ Tapes Foam Types:
Conformable: This foam provides high strength with the capability of conforming to the irregularities of rigid substrates,
even when there might be slight mismatch.
Very Conformable: This foam provides the highest level of conformability while maintaining high internal strength.
Firm: This foam provides the highest level of foam strength in the 3M™ VHB™ Tapes family.
Clear: Not technically a foam, this solid acrylic material provides excellent clarity.

Slitting Tolerance
Standard slitting tolerance ± 1/32 inch (± 0.031 inch, ± 0.8 mm).
Precision slitting with slitting tolerance of ± 1/64 inch (± 0.016 in., ± 0.44 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.

3M™ VHB™ Tapes
Design and Tape Selection Considerations
Choose the right tape for the substrate: Adhesives must flow onto the substrate surfaces in order to achieve intimate
contact area and allow the molecular force of attraction to develop. The degree of flow of the adhesive on the substrate
is largely determined by the surface energy of the substrate.

NOTES: There are a wide variety of formulations, surfaces finishes and surface treatments available on substrate materials which can affect adhesion. This chart is intended
to provide only a rough estimate of the adhesion levels which can be expected on some common materials relative to a reference surface such as aluminum.
Light abrasion of surface will significantly increase adhesion levels on many materials, except when using tapes 4952/4932.
Use the right tape thickness: The necessary thickness of tape depends on the rigidity of substrates and their flatness
irregularity. While the 3M™ VHB™ Tapes will conform to a certain amount of irregularity, they will not flow to fill
gaps between the materials. For bonding rigid materials with normal flatness, consider use of tapes with thickness of 45
mils (1.1 mm) or greater. As the substrate flexibility increases thinner tapes can be considered.
Use the right amount of tape: Because 3M™ VHB™ Tapes are viscoelastic by nature their strength and stiffness is a
function of the rate at which they are stressed. They behave stronger with relatively faster rate of stress load (dynamic
stresses) and will tend to show creep behavior with stress load acting over a long period of time (static stresses). As a
general rule, for static loads, approximately four square inches of tape should be used for each pound of weight to be
supported in order to prevent excessive creep. For dynamic loads, the dynamic performance characteristics provided
on page 4 should be useful, factoring in the appropriate safety factors.
Allow for thermal expansion/contraction: 3M™ VHB™ Tapes can perform well in applications where two bonded
surfaces may expand and contract differentially. Assuming good adhesion to the substrates, the tapes can typically
tolerate differential movement in the shear plane up to 3 times their thickness.
Bond Flexibility: While an advantage for many applications where allowing differential movement is a benefit, the
tape bonds are typically more flexible than alternative bonding methods. Suitable design modifications or periodic use
of rigid fasteners or adhesives may be needed if additional stiffness is required.
Severe Cold Temperature: Applications which require performance at severe cold temperatures must be thoroughly
evaluated by the user if the intended use will subject the tape product to high impact stresses. A technical bulletin
“3M™ VHB™ Tape Cold Temperature Performance” (70-0707-3991-0) is available for additional information.

3M™ VHB™ Tapes
Application Techniques
Clean: Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA*) and
water prior to applying 3M™ VHB™ Tapes.
Exceptions to the general procedure that may require additional surface preparation include:
• Heavy Oils: A degreaser or solvent-based cleaner may be required to remove heavy oil or grease from a
surface and should be followed by cleaning with IPA/water.
• Abrasion: Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt or oxidation
and can increase surface area to improve adhesion.
• Adhesion Promoters: Priming a surface can significantly improve initial and ultimate adhesion to many
materials such as plastics and paints.
• Porous surfaces: Most porous and fibered materials such as wood, particleboard, concrete, etc. need to be
sealed to provide a unified surface.
• Unique Materials: Special surface preparation may be needed for glass and glass-like materials, copper
and copper containing metals, and plastics or rubber that contain components that migrate (e.g. plasticizers).
Refer to 3M Technical Bulletin “Surface Preparation for 3M™ VHB™ Tape Applications” for additional
details and suggestions. (70-0704-8701-5)
*Note: These cleaner solutions contain greater than 250 g/l of volatile organic compounds (VOC). Please
consult your local Air Quality Regulations to be sure the cleaner is compliant. When using solvents,
be sure to follow the manufacturer’s precautions and directions for use when handling such materials.
Pressure: Bond strength is dependent upon the amount of adhesive-to-surface contact developed. Firm
application pressure develops better adhesive contact and helps improve bond strength. Typically, good surface
contact can be attained by applying enough pressure to insure that the tape experiences approximately 15 psi
(100 kPa) pressure. Either roller or platen pressure can be used. Note that rigid surfaces may require 2 or 3 times
that much pressure to make the tape experience 15 psi.
Temperature: Ideal application temperature range is 70°F to 100°F (21°C to 38°C). Pressure sensitive
adhesives use viscous flow to achieve substrate contact area. Minimum suggested application temperatures:
• 50°F (10°C): 3M™ VHB™ Tapes 4950, 5952, 4910, 4952, 4611, 4622 families.
• 60°F (15°C): 3M™ VHB™ Tapes 4941, 4945 families.
• 32°F (0°C): 3M™ VHB™ Tape 4951 families.
Note: Initial tape application to surfaces at temperatures below these suggested minimums is not
recommended because the adhesive becomes too firm to adhere readily. However, once properly
applied, low temperature holding is generally satisfactory.
To obtain good performance with all 3M™ VHB™ Tapes, it is important to ensure that the surfaces are dry
and free of condensed moisture.
Time: After application, the bond strength will increase as
the adhesive flows onto the surface (also referred to as “wet out”).
At room temperature approximately 50% of ultimate bond
strength will be achieved after 20 minutes, 90% after 24 hours
and 100% after 72 hours. This flow is faster at higher temperatures
and slower at lower temperatures. Ultimate bond strength can be
achieved more quickly (and in some cases bond strength can be
increased) by exposure of the bond to elevated temperatures
(e.g. 150°F [66°C] for 1 hour). This can provide better adhesive
wetout onto the substrates. Abrasion of the surfaces or the use of
primers/ adhesion promoters can also have the effect of increasing
bond strength and achieving ultimate bond strength more quickly.

3M™ VHB™ Tapes
Special Cases:
Rough Surfaces with 3M™ VHB™ Tapes 4932/4952 – 3M™ VHB™ Tapes 4932/4952 were designed to
adhere to many low surface energy substrates. Rough surfaces created by light abrasion or textured molds are
typically detrimental to bond strength with this tape family.
Plasticized Vinyl – Plasticizers compounded in soft vinyl can migrate into adhesives and significantly change
their performance characteristics. 3M™ VHB™ Tapes 4941 and 4945 families have 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).
