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.

— Substrate

High surface energy

— Substrate

Low surface energy

This illustration demonstrates the effect of surface energy on adhesive interfacial contact. High surface energy

materials draw the adhesive closer for high bond strength.

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).
