Thin bonding lets your design shine without bulky fasteners by using a virtually invisible industrial-strength bond to attach materials. Using a tape rather than a liquid adhesive allows you to customize the tape to the precise shape you need for the final design, as well as giving you production flexibility by leaving the liner in place until the second substrate is ready. Double coated or adhesive transfer tapes provide shear strength, conformability and high initial adhesion and have industrial applications in electronics, auto interiors, signage and graphics, sporting equipment and much more.
Visit our Double Sided Tapes page to learn more about the benefits common to all double sided tapes.
The carrier is the material that holds or “carries” the adhesive; in double coated tapes (also called supported tapes) it separates the two adhesives. The carrier can be made of paper, plastic film, tissue or foam, and the type of carrier can be important for applications that need to withstand, as one example, the heat level of a paint-drying process or medical sterilization. Having a carrier in the middle enables two different adhesives to be applied for adhering dissimilar materials that require different bonding properties. Once the adhesive is applied to the carrier a liner is applied over one or both sides to protect the adhesive until the tape is applied.
There is also a class of double sided tapes with no carrier. Adhesive Transfer Tape (sometimes called ATT, transfer tape or unsupported tape) is composed of a thin film of adhesive with a liner over the top so it can be easily handled. As with other double sided tapes, an adhesive transfer tape is applied, then the liner is peeled off to apply the second substrate. With no carrier for separation these thin bonding tapes consist of one type of adhesive, but their overall temperature resistance is not limited by the temperature resistance of the carrier and they are extremely conformable to irregular surfaces.
From climate-controlled offices to harsh outdoor environments, you need high-performance versatility that can withstand whatever conditions customers throw at your products. Whether you’re bonding high surface energy substrates like metals and glass or difficult low surface energy materials like powder-coats and some composites, 3M has a wide variety of durable options for thin bonding – select each tab to learn more.
Tape for Hard-to-Bond Textures
When you need a durable solution that can attach, seal and reduce noise, even with hard-to-bond textures, look to 3M™ Acrylic Adhesive 300MP. This versatile high-performance adhesive brings high initial tack and ease of die-cutting to double-coated tapes for a variety of markets including general industrial, automotive, marine, medical equipment, specialty vehicle, construction finishing and office workspace applications. This adhesive bonds textures and substrates such as:
Tape for Metal and High Surface Energy Substrates
It’s not just your substrates that have to endure heat and repeated use – so does the adhesive. 3M™ Acrylic Adhesive 200MP is a versatile adhesive with excellent shear and peel strength, anti-liting power and resistance to solvents and heat. It stands up to repeated use in applications such as consumer appliances, industrial machinery, automotive, transportation, consumer electronics, healthcare, hospitals, public space communications, graphic overlays and fitness machines. This adhesive bonds a variety of metals and other high surface energy substrates, including:
Tape for Hard-to-Bond Surfaces
Some substrates are just challenging to wet out and stick to, period. 3M™ High-Strength Acrylic Adhesive 300LSE is designed specifically to bond low surface energy substrates securely and reliably with high initial tack and high shear strength in the automotive, electronics, consumer appliance and other industries. The adhesive demonstrates good anti-lifting properties on both flat and curved surfaces made of:
Impact Resistant Tapes
As they say, it isn’t the fall, it’s the sudden stop at the end. Drops, vibration and other impacts do happen, and your displays, housings and components need to withstand them. 3M™ Impact Resistant Tape delivers superior impact and vibration damping along with shear resistance, high peel adhesion and high bonding strength. These tapes are designed to provide good bonding on a wide variety of substrates, including those used in electronics and components such as:
Chemical Resistant Tape
Workouts aren’t just tough on the individual, they’re tough on your electronics those individuals wear. 3M™ Chemical-Resistant Adhesive Transfer Tape 96105CR is chemical-resistant and reliable, designed to stand up to heat, humidity, sweat, corrosion, skin oils, sunscreen and more to keep up with your devices and their wearers. Specific applications for this tape include:
Flexible Printed Circuit (FPC) Tapes
Flexible printed circuits have intricate designs so they keep working time after time, and they need reliable bonds to stay in place for all those repetitions. 3M™ Flexible Circuitry Bonding Solutions serve different combinations of needs, including bonding dissimilar substrates, fast or high-temperature processing, convertability to provide accurate edge profiles, anti-lift tapes for curved or bending surfaces and more. Industries that require bonding for flexible printed circuits include:
Conformable or Clear
Conformable and clear tapes are used to bond screens and displays and have many similar or related applications:
As screens take on more shapes, including curves, you need advanced conformability to bond them. The 3M™ Conformable Double Coated Tapes 934XX family features proprietary technologies that make it more drop-resistant and shock absorbing and offer an exceptional balance of properties such as anti-lifting, chemical resistance, good push-out strength, temporary removability and versatile adhesion to both LSE substrates and high surface energy materials like metal and glass.
Products with backlit or display screens require a clear, clean bonding solution. 3M™ Ultra Clear Double Coated Tapes UCT-50 and UCT-30 are ultra-clear and offer 90% light transmission with just 1.1% haze. They’re produced on a clean room coater to keep your finished design free of dirt, dust and debris, and offer excellent initial tack and good adhesion. They also offer dimensional stability for easy die-cutting and laminating.
You may be able to use tape straight from the roll, but many applications require bonds to be a specific size and shape. A converter will work with you to determine the specific carrier and adhesive for the job, then customize 3M products to the precise format you need for your application. Converted tapes can be supplied as rolls or sheets and can be configured for machine or manual application.
