Guide to Adhesive Tapes & Automotive Electronics (Exterior)

Pressure-Sensitive Adhesive (PSA) & Exterior Automotive Electronics

All of us want safer transportation, and this extra vehicle safety usually comes at a cost - more electronics. Frequently on the exterior of the vehicle, rearview mirror displays, backup cameras, and even advanced driver assistance systems (ADAS) can all add weight and complexity to the vehicle.

How do the automotive and transportation OEMs attach, bond, and seal these electronic devices without adding weight, noise, or even more safety concerns?

The solution could be as close as precision die-cut adhesive tapes.

We're also excited to share that we spoke with Scott Krusinski, Automotive Product Manager for Avery Dennison Performance Tapes, to get the skinny on their new automotive adhesive tapes portfolio.

What can you expect here? We'll learn more about how Avery Dennison adhesive tapes can benefit external automotive electronics applications and how custom die-cut parts from JBC can bring it all together.

You can read the companion post here if you're interested in adhesive tape applications for interior automotive electronics.

Now, if you're ready to dive into adhesive tapes and exterior automotive electronics, let's jump in.

Adhesive Tapes for Automotive Applications: Just the Basics

Pressure-Sensitive Adhesive (PSA) tapes used in automotive applications must be durable, withstand high and low temperatures, and resist UV light. And often, they must be able to bond to low surface energy (LSE) materials like paint systems and polyolefin plastics. Avery Dennison's portfolio for Automotive Electronics draws from a wide range of products that have a legacy in the automotive industry, and we'll also learn more about those.

Adhesive Tapes for Exterior Automotive Electronics: Typical Applications

PSA tapes can attach sensors, cameras, and electronic components to the vehicle or even bond them. Before we dive into the details, let's highlight several typical exterior automotive electronics applications for precision die-cut components made using specialty adhesive tapes.

Sensor Mounting & Sealing

Self-driving vehicles mean more ADAS, cameras, and sensors on vehicle exteriors. Die-cut adhesive tapes can bond these sensors to various locations and substrates. 

Double-coated foam tapes can secure ultrasonic sensors inside the bumper. Double-coated foam tapes are also used to secure cameras, lidar, and radar sensors to different vehicle parts.

Gasketing

A gasket can often be used if a permanent bond is not required for sensor components.

A foam gasket can be bonded with a pressure-sensitive adhesive (PSA) tape to the component for a water-tight seal. Thin bonding tapes make an excellent option for this application.

Glare Reduction

With the inclusion of cameras for ADAS, plastic surfaces in front of the cameras create a glare when the sun reflects off those surfaces.

A felt or flock tape can be applied to the plastic surface in front of the camera to absorb glare.

Heater Films for Heater Bonding and Gap Filling

PTC heaters are flexible circuits printed with conductive ink and polyester film, and they are placed around cameras and sensors to prevent ice build-up.

Because they are thin and flexible, a PSA must be used to bond them to different substrates.

Avery Dennison: Automotive Electronics Tapes Portfolio

How do Avery Dennison’s automotive electronics adhesive tapes help transportation OEMs to produce easy-to-assemble, lightweight, durable electronic components?

According to Krusinski, Avery Dennison assembled their automotive electronics tapes portfolio to address these, and other emerging applications as our vehicles continue to evolve.

The portfolio includes 12 applications, 13 adhesive technologies, 24 tape products, and nine construction styles.  It was built to provide solutions to several common challenges, including:

  • Speed of Assembly – repositionable and with an instant bond
  • Lightweighting – replace mechanical fasteners with thin profile lightweight tapes
  • Durability – seal and fill gaps for ingress protection
  • Noise Reduction – mitigate buzz, squeak, and rattle (BSR) and unwanted noise, vibration and harshness (NVH)
  • Vision and Sensing – reduce glare, manage light, and bond PTC heaters

Avery Dennison Automotive Adhesive Tapes: Product Spotlights

Avery Dennison FT0900X is a single coated flock tape used for glare reduction with ADAS cameras. It can be placed in front of the camera lens on the plastic housing around the camera to reduce glare.

“It is a great combination of an existing automotive-specified material being used for a new application,” said Krusinski. “It is a high-performance low VOC acrylic adhesive and meets many OEM specifications. It performs well against extreme temperatures and bonds to low surface energy materials.”

Avery Dennison FM2132 is a general-purpose acrylic with excellent temperature resistance and durability and the ability to bond to low surface energy plastics.

JBC Technologies & Avery Dennison: The Converter Partner Advantage

JBC technologies ADvantage Converter Partner

 

When you partner with JBC Technologies - an industry-leading materials converter - we will add value to Avery Dennison Automotive Electronics Tapes in several ways.

Our value-added solutions include:

  • Laminating different performance materials to Avery Dennison tapes
  • Creating multi-material composites with Avery Dennison tapes
  • Die-cutting custom shapes
  • Custom part presentations for assembly and automation
  • Rapid prototyping and quick turnaround sampling

 

Here are a few specific application advantages you'll get when you choose to work with JBC Technologies:

  1. The backup camera often needs an EPDM foam gasket to form a watertight seal. Converters can laminate an adhesive to the EPDM foam and then die-cut it into the right shape to speed up assembly.
  2. Ultrasonic sensors often have a circular perimeter design. A converter can die-cut the exact shape needed to achieve a strong bond and a clean appearance.
  3. We are experts in materials selection and can help you match the best materials to your specific application.

“If an OEM needs assistance selecting the right material to meet their application's temperature and humidity resistance requirements, converters can work with multiple material manufacturers to help recommend the right material,” Scott Krusinski, Avery Dennison.
