Automotive Electronic Adhesives

Our hot melt polyurethane gasketing adhesives for automotive infotainment displays can offer:

• Low application temperature of <120°C (248°F): By offering a low application temperature, these infotainment display adhesives are suitable for heat-sensitive electronics and can reduce parts damage likelihood. 
• High temperature resistance: Able to perform in temperatures up to 200°C (392°F), our gasketing adhesives can help increase longevity in applications exposed to high temperatures, such as dashboards.
• Various open times and green strength levels: Because our portfolio is broad, it includes products with different open times and green strength levels, which can help accommodate your manufacturing needs and quickly find a solution.
• Reduced waste potential: Compared to other polyurethanes, our solutions are one-component because they are based on hot melt technology. Because no mixing is required, you can avoid mixing errors and reduce waste potential.

Our experts have formulated Thermelt® low pressure resins for encapsulating automotive interior controls and sensors including doors, handles, seatbelts and tire pressure monitoring systems. These solvent-free solutions can provide:

• High electrical resistance: Our Thermelt automotive electronic resins are formulated to impart electrical resistance to control and sensors, which can minimize conductivity, insulate and protect parts. This helps the electronics maintain proper performance levels during the vehicle’s lifetime.
• Good environmental resistance: These resins are designed to help protect the automotive electronic part from environmental elements, such as dust and moisture, to aid in part longevity.
• UL 94 V0 rating: Our Thermelt products have passed certification testing that ensures they can self-extinguish if an encapsulated sensor starts heating up. By doing it, it helps protect the rest of the vehicle’s safety and performance levels.
• Fast cycle times: As low pressure molding hot melts, Thermelt allows for faster cycle times compared to other methods, which helps keep production lines moving.
• Bio-sourced formulations: Our Thermelt automotive electronic encapsulation resins are formulated with bio-sourced materials; this helps reduce reliance on petroleum-based chemicals.

Additionally, our electronic encapsulation resins may be recyclable under certain conditions; please contact a Bostik expert to discuss further.

For cameras, LiDARs, electronic control units and modules, we offer Polytec PT gap fillers and electrically-conductive adhesives, Born2Bond™ instant adhesives and cure-in-place gasket solutions to help you meet key goals.

Our Polytec PT gap fillers and thermally-conductive adhesives can provide:

• Thermal management: These automotive electronic solutions are formulated to dissipate heat, helping to decrease likelihood of parts overheating, which can extend longevity while improving safety.
• Low abrasion: These automotive electronic products are low abrasive, which can reduce equipment wear and tear
• Low viscosity: One of our Polytec PT solutions has low viscosity formulation, which can help with dispensing ease and reduce equipment maintenance, associated downtime and energy usage.
• Removability: Our gap fillers are formulated to be removable to help with repairs and minimize waste.

Our Born2Bond™ instant adhesives are cyanoacrylates that work well for cameras, LiDARs, electronic control units and modules and can offer:

• Environmental protection: Our Born2Bond™ instant adhesives are formulated to provide moisture, humidity and temperature resistance to aid in electronic part longevity.
• Chemical resistance: These automotive electronic adhesives can withstand automotive fluids, industrial chemicals and cleaning agents to help improve parts performance.
• Instant adhesion: As instant adhesives, Born2Bond™ automotive electronic adhesives set quickly to help keep production lines moving.

In addition to providing quality automotive electronic adhesives and as the adhesive solutions segment of Arkema, we offer:

• A one-stop-shop approach to automotive adhesives: Our adhesive portfolio for automotive interiors spans applications including interior trim, EV batteries and more. This means you can rely on us across your adhesive application needs, which can help streamline logistics.
• Extensive technical and analytical support: Our experts will work with you step-by-step to help ensure testing, trials and product startup runs smoothly. We can also help with any troubleshooting that may be needed and identify ways to help mitigate the issues in the future. Further, we can customize solutions tailored specific to your application needs and OEM specifications.
• Regional product availability: Our local manufacturing capabilities help ensure you can get the products you want where and when you need them.
• Collaboration with low pressure molding equipment manufacturer: By working closely with an equipment supplier, we can optimize our products for low pressure molding equipment. For example, this allows the design of the mold to meet the characteristics of the low pressure resin and vice versa.
