Bonding and Assembly

Appliances offer many opportunities for adhesives and tapes to replace mechanical fasteners, particularly for exterior panel and control panel bonding, wire bundling and gasketing or sealing.
 

• 3M™ Scotch-Weld™ Structural Adhesives can replace welding while threadlockers can make sure the bolts you do use stay in place.
• 3M™ VHB™ Tapes can be used for bonding and at the same time create a seal around glass window panels.
• 3M™ Aluminum Foil Tapes can be used to deflect heat from sensitive locations while (splitting this into two bullets)
• Scotch® Strapping Tapes can be used to secure racks, cords and wire bundles during production and shipping.

Panel-to-Frame applications include bonding top and side panels to the appliance frame.

Large Surface Lamination may be used to fabricate lightweight multi-material panels or panels with different layers such as insulation.

Gasketing and Sealing may be necessary to keep water or coolants inside the appliance where they belong.

Whether you need spaces for buttons or a viewing screen or a shape cut precisely to fit a piece of trim, using our products straight from the factory isn’t always an option. Strips of tape aren’t suitable for every application and liquid adhesives may not be precise enough. The solution is to work with a converter to get just the right adhesive in the right shape. Your converter can work with both your expert team and ours to help you determine the best adhesives for joining your substrates, then convert our rolls or sheets of tape to the right shape and size for your production line, part after part after part.

Electronics always have their eye on the future, with devices optimized for IoT, 5G and beyond. 3M has a full range of products to help you navigate that future whether you’re developing a smartphone, tablet, Bluetooth speaker, wearable or smart home device. Spend less time worrying about material capabilities and more time focusing on what your customers desire most — a reliable device with unhindered functionality.

Metalworking and metal fabrication includes everything from large items like machinery construction and architectural panels down to small items like sporting equipment and metal furniture. While bare metal is generally easy to bond, it’s important to remember that any paint, dirt or oily coating will make bonding more difficult, and of course the second substrate may also be challenging to bond. 3M has adhesives and tapes to address many different metalworking needs. Some of the main families include:
 

• 3M™ Scotch-Weld™ Structural Adhesives that provide over 1000 psi of overlap shear strength
• 3M™ VHB™ Tapes that offer instant strength plus viscoelasticity to allow thermal expansion and contraction
• 3M™ Spray Adhesives that can be sprayed, brushed or rolled onto large areas

Panel-to-Frame applications involve bonding load-bearing panels to rigid frames in locations such as elevator walls, architectural panels and glazing, and large metal enclosures such as HVAC or electrical equipment.  Some applications also involve Stiffener-to-Panel bonding in order to reinforce the panel.

Small Joint Assembly applications are often irregularly shaped joints with only a few inches that overlap. These can be insertion or overlap joints or some combination and include such functions as mortise and tenon furniture joints, thread locking and air or liquid ducting and piping.

Large Surface Lamination involves two surfaces of similar size where the majority of the matching surface is covered with an adhesive. Applications include laminations for doors, bonding foam and fabrics for seating and general fabrication of insulated, composite or sandwich panels.

Mounting and Trim Attachment applications involve applying smaller objects to larger surface, including frames, small signs, mirrors and white boards.

Specialty vehicles include rolling containers such as semi-trailers, box trucks, cargo trailers and horse trailers as well as emergency vehicles like ambulances and fire trucks. These vehicles need tough, durable bonding solutions that can withstand weather, extreme temperature fluctuations and constant road vibration, and they may also require final structural strength or need to meet specific challenges related to the assembly process. In addition, adhesive and tape solutions can bond newer lightweight materials and provide a smooth surface with an unnoticeable bond compared to mechanical fasteners with exposed heads. Product families that can help meet these needs include:
 

• 3M™ Scotch-Weld™ Structural Adhesives that provide over 1000 psi of overlap shear strength
• 3M™ VHB™ Tapes that offer instant strength plus viscoelasticity to allow thermal expansion and contraction
• 3M™ Spray Adhesives that can be sprayed, brushed or rolled onto large areas

Panel-to-Frame applications involve bonding walls and ceiling or roof panels to rigid frame structures. Some situations may also require Stiffener-to-Panel bonding, where a stiffener is used to reinforce a panel.

Large Surface Lamination applications include seat construction, headliner installation and interior panel padding.

Sealing applications can involve using tapes and adhesives that also create a seal or applying sealants to exterior surfaces and joints to prevent water intrusion.

Buses and passenger rail cars offer many opportunities for adhesive and tape solutions, from bonding panels to the frame to constructing seats to attaching signage. 3M bonding and assembly solutions can help with worker and passenger safety, lightweighting, durability and providing passengers with a more comfortable experience – all while helping to make your manufacturing, maintenance and refurbishment processes faster and cleaner. Product families that can help meet these needs include:
 

• 3M™ Scotch-Weld™ Structural Adhesives that provide over 1000 psi of overlap shear strength
• 3M™ VHB™ Tapes that offer instant strength plus viscoelasticity to allow thermal expansion and contraction
• 3M™ Spray Adhesives that can be sprayed, brushed or rolled onto large areas
• 3M™ Dual Lock™ Reclosable Fasteners for access panels or replaceable sections

Panel-to-Frame applications involve bonding walls and ceiling or roof panels to rigid frame structures. Some situations may also require Stiffener-to-Panel bonding, where a stiffener is used to reinforce a panel.

Large Surface Lamination applications include flooring, seat construction and layered, insulated or composite interior panels.

Sealing applications can involve using tapes and adhesives that also create a seal or applying sealants to exterior surfaces and joints to prevent water intrusion.

Mounting and Trim Attachment applications involve applying smaller objects to larger surfaces, including for things such as fold-down trays, overhead luggage compartments and signs.

Signs are everywhere from large highway signs to small nameplates and serving purposes from guidance to advertising. All these signs need to be attached, and 3M can help you do it without mechanical fasteners. In addition to bonding substrates such as glass and certain plastics where mechanical fasteners are difficult to use, adhesives and tapes provide a hidden bond for better aesthetics and can help resist bimetallic corrosion by keeping substrates separate. Similar applications include bonding and sealing glass in deli and display cases and vending machine windows. Depending on the strength, durability and other properties you need for a specific situation, different 3M product families provide excellent bonding solutions:
 

• 3M™ Scotch-Weld™ Structural Adhesives that provide over 1000 psi of overlap shear strength
• 3M™ VHB™ Tapes that offer instant strength plus viscoelasticity to allow thermal expansion and contraction
• 3M™ Dual Lock™ Reclosable Fasteners provide good holding strength while also being separable for signs that are removed and replaced periodically

Panel-to-Frame applications involve bonding load-bearing panels to rigid frame structures. Some situations may also require Stiffener-to-Panel bonding, where a stiffener is used to reinforce a panel.

Mounting and Trim Attachment applications involve applying smaller objects to larger surfaces, including items such as mirrors, white boards and small directional signs.

Sealing may be an added benefit for applications such as refrigerated cases, where the tape or adhesive bond can also seal out warm air.
