  • Virtually invisible fastening – Aesthetics can be improved through thinner, cleaner bond lines.
  • Increased material options – Lighter or dissimilar materials can be used with 3M Tapes and Adhesives to achieve a lower total delivered cost.
  • Increased manufacturing efficiency – Reduce or eliminate riveting, drilling, welding, surface finishing and cleanup in many applications. Often bonding, sealing and gap filling can be incorporated into one step.

Our technical and sales teams can work closely with customers to help optimise production methods, improving productivity and product performance.

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 specifi c 3M adhesives and tapes for your operation.

What types of materials are you joining?
Some materials are harder to bond than others. But with 3M adhesive and tape technologies, even many materials once defined as “hard-to-bond”, such as low surface energy plastics can be bonded, with strength in some cases greater than the materials bonded.

Can adhesives hold together the materials you want to join with the strength you need?
Strength can be readily matched to the substrate and stress or “load” characteristics to which the bond will be subjected to. The strength required will be a function of the load applied to the area of bond. 3M have a range of chemistries that give a range of “strengths”. You can match the loads that will be applied to the strength of a 3M adhesive.

What type of load will be applied?
Most adhesives and tapes perform better when the primary stress is tensile or shear, however in most industrial applications, a combination of stresses are involved that may include cleavage and peel. Many of the technical data tables provided in this guide include details of shear strength, tensile strength & peel strength, and may assist in selecting adhesives with the right characteristics for the primary load types.

Do you want to eliminate the stress concentration caused by spot welds, rivets, screws, or other mechanical fasteners and maintain surface integrity?
Adhesives distribute stress evenly over the entire bonded area. A rivet or screw hole in the substrate concentrates stress at the hole and can decrease some 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. Elimination of holes in metal also reduces the chance of rust and corrosion.

Would invisible fastening improve your products 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.

Do you want to attach dissimilar substrates?
Laminates of dissimilar materials 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 between such materials as aluminum and wood.

Is the design of your component right for adhesive bonding?
Adhesives perform better with some component configurations than with others. With the variety of 3M adhesive forms such as pastes, aerosol sprays, and tapes, you should be able to find an adhesive to meet the requirements of most parts that can be assembled with mechanical or fusion fastening. A spray adhesive would be effective, for example, to cover foam cushioning, but would not be a consideration for a part with a narrow bonding area. For cleaner, more efficient application, die-cut pressure sensitive adhesive foam tape can be precisely placed on smaller, irregularly shaped bonding surfaces.

Will your fi nished 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.

Do you need high speed bonding?
In some instances, adhesive bonding can be slow and require critical processing. Some epoxies, for example, require heat, pressure and fi xturing to bond metal to metal in structural strength assemblies. With the wide range of 3M adhesives and tapes, however, a variety of open times are available. Depending on your end use requirements, you can select 3M pressure sensitive adhesives that bond on contact or a 3M two-part paste adhesive with open times ranging from 2 to 90 minutes. Repositionable formulations are also available for repeated openings and closings.

Will your part be subjected to vibration?
The viscoelasticity of many 3M adhesives and tapes improves resistance to vibration fatigue by imparting fl exibility to a joint or bonded area.

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, welding, screwing, finishing, and similar operations.In most cases, adhesives require minimal training, and many adhesives require little or no investment in major equipment.

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. Adhesives and tapes also provide a fi lm barrier to reduce or prevent bimetallic corrosion that often occurs in bonding two different types of metal.

Does your part need to be disassembled for maintenance or service?
When assembled with most adhesives or tapes, parts are generally difficult or virtually impossible to disassemble without damaging the part. As an exception, hot melt adhesives can be reheated and reused, but in most instances reuse would be messy and impractical. As already noted, repositionable adhesives are
available, but application is restricted to lighter duty attachment or closure. Reclosable fasteners are a hybrid technology using mechanical fastening and pressure sensitive adhesive. The adhesive permanently bonds two reclosable mating strips to the substrates that need to be opened and closed.

3M Adhesive and Tape Classifications
Classify by form:
3M adhesives are available as liquids, pastes, tapes, films, and shaped solids. Each has characteristics to be considered for
application effectiveness and efficiency. Liquids and pastes readily fi ll voids to enhance mechanical adhesion. Many liquids can be sprayed to cover large areas.
Films and pressure sensitive tapes offer advantages unique to their form:

  • Uniform thickness throughout the joint.
  • Confinement of the adhesive to the immediate bonding area.
  • Clean bonding without dripping or overflow.
  • Minimum adhesive waste.
  • Die-cut into unique shapes to facilitate bonding of complex parts with narrow bonding surfaces.

Hot melts are supplied as solid sticks, cartridges, pellets, or similar shapes. Handling and storage is easy and neat.

Classify by strength
Another classifi cation for industrial applications is by relative strength and solidifi cation process. Generally, those adhesives that bond through a chemical reaction are stronger than those that bond through a physical change.

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

  • Epoxy adhesives are available in one and two-part liquids and pastes. Of all 3M adhesives, these provide the highest strength and elevated temperature resistance.
  • Acrylic adhesives are two-part liquids or pastes that bond the widest variety of substrates including hard-to-bond plastics and oily metals. The distinction is high strength bonding without the surface preparation needed for epoxies and urethanes.
  • 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.

Non-structural adhesives bond with a physical change.
Non-structural adhesives vary in strength from repositionable to equal to or greater than the strength of the substrate being bonded. These adhesives are typically less than 1,000psi and bond materials in cushions, gaskets, insulation, veneers, and general assembly. 3M formulations include the following:

  • Hot melt adhesives melt and fl ow under heat to wet the substrates and make bonds quickly upon cooling. Products are available with a variety of characteristics such as short set times, sprayable formulas, and permanent PSA properties. Applications range from sealing to bonding automotive interior
    trim.
  • Rubber adhesives are solvent-based or water-based and solidify through evaporation of the carrier. Products are designed for: adhesion to various substrates; a variety of application methods; and environmental resistance.
  • Contact bond adhesives are usually rolled, brushed, or sprayed on the two surfaces to be mated and permitted to become dry to the touch with a variety of open times. When the surfaces are pressed together, near ultimate bond strength is achieved.

Pressure sensitive adhesives
Pressure sensitive adhesives (PSAs) found in 3M tapes grip immediately to mating services. With dwell time, the adhesive conforms to surface irregularities.

3M hybrid classifications

  • Curing hot melts (Polyurethane Reactive [PUR] adhesives) are moisture-curing urethanes that apply like a hot melt adhesive but cool to bond strength usually associated with two-part structural adhesives.
  • Reclosable fasteners combine adhesive and mechanical fastening principles. Pressure sensitive adhesive permanently bonds two reclosable mating strips to the substrates that need to be opened and closed multiple times.

Tape Selection Guide

Adhesive family selection based on surface energy
Adhesives attach to the surfaces of two substrates, unlike a process that fuses substrates into a unified whole such as welding metal or solvent activation of plastics. In selecting a 3M adhesive or tape, surface condition must be considered: roughness, smoothness, porosity, coated, uncoated, cleanliness, flexibility, size of the part and surface energy of the part.

Adhesive paste, for example, flows readily into a rough surface for improved effective adhesion. Flexible materials such as paper or thin gauge metal can be bonded with a thin adhesive transfer tape. Large rigid parts with smooth clean surfaces can be bonded with a variety of 3M products ranging from double coated foam tapes to two-part structural adhesives. Some plastics have plasticisers which migrate to the surface and degrade the bond over time, so a plasticiser-resistant adhesive or tape is essential. If the substrate has been powder coat painted, the coating is the bonded surface rather than the substrate and you would want to consider a 3M tape or adhesive developed specifically for that surface.

Surface energy ranges from high to low. To illustrate the concept of surface energy, think of water on the unwaxed bonnet of a car. The unwaxed bonnet has high surface energy and water on the hood flows into puddles. In comparison, a waxed hood has low surface energy and water beads up rather than fl ows out. Similar to water, adhesive on a high surface energy surface fl ows and “wets out” the surface. “Wetting out” is required to form a strong bond. As a rule of thumb, the higher the surface energy, the greater the strength of adhesion.

Specially formulated adhesives are available for low surface energy surfaces. The following illustrations and surface rankings give you an idea of relative surface energy.

Regardless of surface energy, the substrate must be unifi ed, dry, and clean to maximise adhesive contact.
