Electric Vehicle Battery Assembly Creates New Bonding Demand
Battery pack assembly requires thermal interface materials, cell-to-cell bonding, and structural adhesives sealing the pack enclosure, a demand category with no direct precedent in internal combustion vehicle manufacturing. Each battery pack uses several kilograms of specialty adhesive across these functions, and formulation requirements differ meaningfully by cell chemistry and pack architecture, which keeps qualification cycles long and supplier relationships sticky once established. Henkel, 3M, and Dow have all expanded battery-specific adhesive portfolios considerably in response. The commercial consequence is a genuinely new revenue pool growing directly with electric vehicle production volume rather than with the broader automotive adhesive base.
Market Impact: Adhesive use rises 2.5 kg
