Key Findings
TESA’s advanced automotive adhesive solutions are delivering essential innovations in car design and assembly, driven by the rapid transition to electric vehicles (EVs) and the evolution of sophisticated human-machine interfaces (HMIs). These adhesives provide the foundational elements for ensuring durability, weight reduction, and reliability across a wide range of automotive applications, including critical EV battery assembly.
Technical Details
- TESA’s extensive adhesive portfolio covers a broad spectrum of functionalities:
- Bonding and Mounting: Securely fastens components, providing structural integrity.
- Masking and Protection: Offers precise masking in processes like painting and acts as a protective layer against external damage.
- Sealing: Prevents ingress of water, dust, and noise, enhancing cabin comfort and component longevity.
- Thermal Management: Efficiently dissipates heat from EV batteries, crucial for maintaining battery performance and safety.
- Grounding and Shielding: Provides electrical grounding to prevent electronic malfunctions and offers electromagnetic shielding.
- Hole Covering: Effectively seals openings in vehicle bodies and components, balancing aesthetics with functionality.
- Compared to traditional mechanical fastening methods, these adhesives contribute to overall vehicle lightweighting by reducing the number of parts and simplifying assembly processes. Lightweighting is directly linked to extended driving range and improved energy efficiency in EVs.
- In EV battery assembly, specific adhesives such as thermally conductive and flame-retardant types play vital roles in securing battery cells, preventing thermal runaway, and ensuring waterproofing and dustproofing. This ensures the safety and long-term performance of the battery system.
Background & Context
The automotive industry is undergoing a once-in-a-century transformation driven by the “CASE” trends: Connected, Autonomous, Shared, and Electric. For EVs, battery pack safety, efficiency, and lightweighting are paramount, while HMI advancements are directly linked to improved information delivery and usability for drivers and passengers. Addressing these new requirements necessitates advanced material solutions like adhesives, as traditional fastening methods such like welding or screwing alone are proving insufficient.
Strategic Significance & Outlook
TESA’s advanced automotive adhesives will increasingly play a critical role in the evolution of the automotive industry. As EV battery technology continues to innovate, in-vehicle HMIs become more sophisticated, and autonomous vehicles become widespread, there will be an escalating demand for adhesives with superior functionality, reliability, and manufacturing efficiency. TESA aims to remain a core partner in supporting the safety, performance, and sustainability of next-generation vehicles by addressing these technological challenges.
