Automotive Adhesives and Sealants Market Forecast 2035 | Structural Adhesives, Windshield Bonding, EV Battery Module Adhesives, Underbody Sealants and NVH Sealants for Passenger Vehicles, Commercial Trucks and Electric Vehicle Platforms

The automotive adhesives and sealants market encompasses structural epoxy adhesives for body-in-white bonding, polyurethane windshield and glass bonding adhesives, EV battery module adhesives and thermal interface adhesives, anti-flutter and hem flange adhesives, underbody PVC and acoustic sealants, and seam sealers for corrosion protection in passenger vehicles and commercial trucks. The global automotive adhesives and sealants market is projected to reach USD 14.8 billion by 2035 at a 7.2% CAGR, driven by structural adhesive bonding replacing spot welding in multi-material vehicle body construction, EV battery module adhesive and thermal interface material demand scaling with EV production, and lightweight multi-material vehicle architectures combining aluminium, CFRP, and high-strength steel requiring adhesive joining rather than conventional resistance spot welding.

Automotive adhesives are enabling the multi-material vehicle lightweighting revolution — aluminium cannot be spot-welded to steel, CFRP cannot be resistance-welded at all, and the complex mixed-material body structures of modern EVs and lightweight ICE vehicles require structural adhesive bonding as the primary joining method. Structural adhesive bonding in multi-material vehicles replaces 400-600 spot welds per body-in-white with continuous adhesive bond lines providing 40-50 percent improvement in body stiffness, improved NVH performance through vibration isolation, and galvanic corrosion barrier between dissimilar metals compared to direct metal-to-metal contact at spot weld locations.

Consultant POV

“Automotive adhesives are the hidden infrastructure of multi-material vehicle construction. Every Tesla aluminium body, every BMW CFRP floor, every Audi aluminium space frame is bonded as much as it is welded. Henkel dominates this market with extraordinary breadth — Terokal structural adhesive, Teroson glass bonding, and Bergquist thermal interface adhesive together cover most of the automotive adhesive value chain. The EV battery adhesive opportunity is the fastest-growing segment because every battery pack is a chemical bonding engineering challenge: cell bonding, module bonding, thermal interface, and housing sealing are all adhesive-dependent. The first adhesive system combining structural bonding, thermal conductivity, and electrolyte resistance in a single formulation owns the cell-to-module bonding standard.”
