Specialty Tapes

Technical Data August 2018

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.

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).

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 (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 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.

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.

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.

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. 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 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, 4910, 4952, 4611, 4622 families.

• 60°F (15°C): 3M™ VHB™ Tape 4945 family.

• 32°F (0°C): 3M™ VHB™ Tape 4951 family.

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.
