-Authorized converters help you adapt many 3M products to meet special requirements for shape, size, and production.

Knowing when to use 3M adhesives and tapes to improve your product and process

Based on your answers to the following questions, you can decide if it will be worth your time to evaluate specific 3M adhesives and tapes for your medical device.

Q.Can adhesives hold together the materials you want to join with the strength you need?

Some materials are harder to bond than others. But with 3M adhesive and tape technology, even many materials once defined as “hard-to- bond,” such as low surface energy plastics, can be bonded with strength greater than the materials bonded.

Q.Do you want to eliminate the stress concentration caused by screws or other mechanical fasteners and maintain surface integrity?

Adhesives distribute stress evenly over the entire bonded area. A screw hole in the substrate concentrates stress at the hole and can decrease physical properties of the substrate. With uniform stress distribution of adhesives and tapes, lighter, thinner materials can be used without concerns about distortion, splitting, or crazing at the mechanically fastened site.

Replacement for mechanical fastening – At 250 psi, overlapped plastic panels elongate at the rivets. With 3MScotch-Weld Structural Adhesive DP-8005, stress is distributed evenly and panels maintain continuous contact.

Q.Would invisible fastening improve your device’s appearance?

3M adhesives and tapes are generally hidden between the bonded substrates. Surfaces stay smooth and clean for a more attractive appearance and less surface refinishing.

Q.Do you want to attach dissimilar substrates?

Laminates of dissimilar material can often produce combinations superior in strength and performance to either substrate alone. The flexibility of many 3M adhesives and tapes compensates for differences in the coefficients of expansion and also provide a film barrier to reduce or prevent bimetallic corrosion that often occurs in bonding two different types of metal.

Q.Will your device be subjected to vibration?

Many 3M adhesives and tapes provide a viscoelastic response to a dynamic stress which can attenuate resonant vibrations, resist fatigue, and impart flexibility to a joint or bonded area.

Q.Do you want to bond and simultaneously seal between the substrates?

With many adhesives and tapes, continuous contact between mating surfaces effectively bonds and seals against dirt, dust, water, and other environmental conditions.

Q.Will your finished assembly be exposed to harsh environmental conditions?

Some adhesives do not hold well when exposed to very low or very high temperatures, high humidity, chemicals, or even water. Other adhesives are specially formulated to resist harsh environments.

2

Assembling the more competitive device

Q. Do you want to cut costs, increase production and simplify your operation?

With 3M adhesives and tapes, you can see cost reduction through reduced material requirements, weight reductions, and elimination of drilling, screwing, finishing, and similar operations. In most cases, adhesives require minimal training. And many adhesives and tapes require little or no investment in major equipment.

Knowing which type of a 3M adhesive or tape product to use

Narrowing choices to a few products to evaluate for your specific medical device, starts with only two questions and answers:

Q.Does your device need to be disassembled for maintenance or service?

When assembled with most 3M adhesives or tapes, parts are generally difficult or virtually impossible to disassemble without damaging the part. With 3MReclosable Fasteners, substrates can be attached and unattached, opened and closed, or repositioned many times.

Q.For permanent assembly, do you need structural or non-structural strength?

3M structural strength adhesives bond the load-bearing parts of a product by chemical reaction. As a rule of thumb, structural strength adhesives reach a minimum of 1,000 psi overlap shear strength. 3M formulations include the following:

Epoxy adhesives provide the highest strength and elevated temperature resistance of all 3M adhesive pastes.

Acrylic adhesives bond the widest variety of substrates including hard-to-bond plastics. The distinction is high strength bonding without the surface preparation needed for epoxies and urethanes.

Urethane adhesives are generally lower cost and cure quickly to an elastic bond in applications requiring flexibility between dissimilar materials. Impact resistance is a distinctive characteristic.

Cyanoacrylate adhesives are high strength liquid formulations known as instant adhesives. On rigid plastic, glass, metal, rubber, and other low porosity substrates, they harden in seconds through reaction with surface moisture.

Each structural adhesive has high cohesive strength to bond high strength materials and potentially replace mechanical fasteners. With the range of adhesive, you can bond virtually any material used in medical device assembly.

3M non-structural adhesive products bond by physical change non-load-bearing materials such as gasketing and veneering, and loadbearing materials where stress is below 1,000 psi in overlap shear.

Pressure sensitive adhesives (PSAs) found in 3M tapes and labels grip immediately to mating surfaces. With dwell time, the adhesive conforms to surface irregularities. The PSA in some 3MVHBTapes can reach overlap shear strength of more than 900 psi.

3M Scotch-Weld Structural Adhesives

Load-bearing formulations for metal, plastic, rubber, and more

As an alternative to mechanical or fusion fastening, the reasons for 3MScotch-Weld Structural Adhesives are many: greater design latitude, cleaner lines, material substitution, less machining, lighter weight, more durability, and often less cost.

Whatever properties you need – durable adhesion, flexibility, creep resistance, heat and environmental resistance, void-filling—you’ll likely find a 3M Scotch-Weld Product to meet your requirements and expectations.

3M proprietary adhesives have been proven in membrane switches for over 20 years. Features of the line include –

Exceptionally high cohesive strength for long-term resistance to the stress of switch actuation.

Outstanding resistance to hostile environments such as high humidity and moisture, extreme temperature ranges, and/or UV light.

Excellent resistance to chemicals, detergents, cleaners, and solvents.

3M adhesives are available for graphic overlay attachment, die-cut laminations in switch contact areas, double-coated spacers for circuit separation, and singlecoated spacers for switch assembly. Single-coated products seal and bond for circuit layers, metal dome placement, and lead protection.

NOTE: The technical information and data provided here should be considered representative or typical only and should not be used for specification purposes. User should evaluate the 3M product to determine whether it is fit for a particular purpose and suitable for user’s method of application.

*Products in this family are 3MVHBTapes offering 3M’s highest strength.

All PSA products are on film liners (except SJ4570 and SJ3506/07 have paper liners) – four square inches of fastening area per pound of static load is a suggested starting point.

Rubber adhesives are suited for indoor applications or attachments to low surface energy (LSE) materials such as polyethylene, polypropylene, powder coated paints, etc. Acrylic adhesives are better suited for high temperature or high humidity applications.

* Not available in 250. See Dual Lock Mix and Match Program for alternate adhesives – Refer to Fastening Price Pages.
