Introduction

At the Battery Show North America 2025, taking place in Detroit from October 6 to 9, Wacker Chemical Corporation (WCC) is set to present its state-of-the-art thermally conductive (TC) adhesives. This demonstration underlines WACKER's dedication to advancing electric vehicle (EV) battery technology at a time when the industry is shifting towards innovative battery architectures such as cell-to-pack (CTP) and cell-to-chassis (CTC) designs.

The Need for High-Performance Adhesives

As the EV market expands and evolves, the necessity for high-performance adhesives that can offer thermal management while maintaining structural integrity is increasingly crucial. WACKER's new TC adhesives are designed to meet these rising demands effectively. These adhesives not only provide essential thermal conductivity but also offer superior mechanical properties, aiding in the performance and safety of EV batteries.

Advancements in Adhesive Technology

One of the highlights from WACKER's presentation will be its proprietary hybrid thermally conductive adhesives that utilize silane-terminated polyether (STP-E) technology. This cutting-edge development combines the flexibility and resilience of silicone materials with the robustness of organic polymers. The resultant hybrid adhesives are customizable, featuring high thermal conductivity, chemical resistance, and flame retardance—key characteristics that enhance overall EV battery safety and efficiency.

Peter Zorney, the Senior Director responsible for WACKER's Electronics and Automotive segment in North and Central America, expressed that, "As electric vehicle battery architectures evolve, WACKER's thermally conductive adhesives are designed to anticipate industry trends, such as new vehicle assembly methods and total value optimization."

Benefits of WACKER's Hybrid TC Adhesives

Unlike traditional adhesives like epoxy or polyurethane, WACKER's hybrid adhesives are free from isocyanates, solvents, and tin, making them more user-friendly and safer for application. They are engineered to uphold their high adhesive strength and flexibility even after long-term exposure to extreme temperatures and humidity, which is increasingly important as the latest battery designs are more vulnerable to environmental challenges.

Meeting the Challenges of New Battery Designs

As the transition from conventional cell-to-module (CTM) designs to advanced CTP and CTC configurations occurs, the requirements for thermal interfaces and adhesives are rapidly evolving. WACKER's newly developed thermally conductive adhesives are tailored to address current industry trends, including lightweighting, cost reduction, and enhanced simplicity in application.

Conclusion

Wacker Chemical Corporation is set to take a significant step in the EV sector with its introduction of next-gen thermally conductive adhesives at the Battery Show North America 2025. By focusing on innovative solutions that adapt to the quickly changing landscape of electric vehicle technology, WACKER is poised to play a pivotal role in enhancing the efficiency, safety, and performance of future EVs. Attendees are encouraged to visit WACKER at Booth 5011 to explore these cutting-edge adhesive technologies firsthand.
