VHB™ Tape - Specialty Tapes
September 2022

Technical Data
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 stressrelaxing 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 peeladhesion, 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 ToleranceStandard 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 alsoavailable 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 LifeAll 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 mostproducts this is found as the 4 digits after the “9” following the product number. For tapes printed continuously around thecore (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 predictedby accelerated aging of assembled parts at 150°F (66°C) for one week).

3M™ VHB™ Tape - Specialty 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.
Foam type can affect and/or limit maximum adhesive strength.

Use the right tape thickness: The necessary thickness of tape depends on the rigidity of substrates and their flatness irregularity. Whilethe 3M™ VHB™ Tapes will conform to a certain amount of irregularity, they will not flow to fill gaps between the materials. For bonding rigidmaterials 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 (57 cm2 of tape per kg) 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 typicallymore flexible than alternative bonding methods. Suitable design modifications or periodic use of rigid fasteners or adhesives may beneeded 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.

Application Techniques
Clean: Most substrates are best prepared by cleaning with a 50:50 mixture of isopropyl alcohol (IPA*) and water prior toapplying 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 andshould be followed by cleaning with IPA/water.
• Abrasion: Abrading a surface, followed by cleaning with IPA/water, can remove heavy dirt or oxidation and canincrease surface area to improve adhesion. Abrasion is not suggested with 3M™ VHB™ Tapes 4932 and 4952.
• 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 andsuggestions. (70-0704-8701-5)*Note: These cleaner solutions contain greater than 250 g/l of volatile organic compounds (VOC). Please consult yourlocal 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 applicationpressure develops better adhesive contact and helps improve bond strength. Typically, good surface contact can beattained by applying enough pressure to insure that the tape experiences approximately 15 psi (100 kPa) pressure. Eitherroller or platen pressure can be used. Note that rigid surfaces may require 2 or 3 times that much pressure to make thetape 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, 4910, 4611, 4622 families.
• 60°F (15°C): 3M™ VHB™ Tape 4945 family.
• 32°F (0°C): 3M™ VHB™ Tape LSE or 4951 family (Note: Surface must be frost free).
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 temperatureholding is generally satisfactory.
To obtain good performance with all 3M™ VHB™ Tapes, it is important to ensure that the surfaces are dry and free ofcondensed moisture.
Time: After application, the bond strength will increase as theadhesive flows onto the surface (also referred to as “wet out”).
At room temperature approximately 50% of ultimate bondstrength will be achieved after 20 minutes, 90% after 24 hours
and 100% after 72 hours. This flow is faster at higher temperaturesand slower at lower temperatures. Ultimate bond strength can beachieved more quickly (and in some cases bond strength can beincreased) 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 ofprimers/ adhesion promoters can also have the effect of increasing
bond strength and achieving ultimate bond strength more quickly.
