Wacker Chemical Corporation (WCC) is showcasing its latest advancements in thermally conductive (TC) adhesive technology at The Battery Show North America 2025, reinforcing its commitment to driving innovation in electric vehicle (EV) battery systems. The event takes place in Detroit, Michigan, from October 6 to 9.

As the EV industry rapidly transitions from traditional cell-to-module (CTM) configurations to next-generation cell-to-pack (CTP) and cell-to-chassis (CTC) designs, the need for adhesives that deliver superior thermal management and structural performance has become increasingly critical. Responding to these evolving demands, Wacker is expanding its product portfolio with a new line of thermally conductive adhesives (TCA) designed specifically for advanced EV battery applications.

Wacker’s silicone and hybrid adhesive technologies are engineered to provide both essential heat dissipation and robust mechanical stability. The company’s proprietary hybrid TC adhesives, formulated with silane-terminated polyether (STP-E) technology, combine the flexibility and temperature resistance of silicones with the mechanical strength of organic polymers. This unique material design enables customizable curing profiles, high thermal conductivity, excellent chemical resistance, and flame retardance—essential features for enhancing both the safety and performance of electric vehicle batteries.

“As EV battery architectures evolve, Wacker’s thermally conductive adhesives are developed to stay ahead of industry trends, supporting new assembly methods, re-workability, and overall value optimization,” said Peter Zorney, Senior Director of Electronics and Automotive for North and Central America. “Our silicone-based adhesives have demonstrated stable mechanical performance even after extensive thermal aging and shock testing, ensuring long-term reliability and safety for electric vehicles.”

With its next-generation TC adhesive solutions, Wacker continues to support the advancement of sustainable mobility by enabling efficient, reliable, and thermally optimized battery systems for the vehicles of the future.
