Automotive Adhesives And Sealants Market

Market Data

The global automotive adhesives and sealants market size was USD 12.80 Billion in 2025 and is expected to register a revenue CAGR of 6.6% during the forecast period. Market revenue growth is supported by EV platform battery module encapsulation and thermal gap pad bonding consuming three to five kilograms of reactive polyurethane and epoxy adhesive per vehicle above the ICE adhesive load, Henkel Adhesive Technologies generating approximately 20% of its EUR 11 Billion 2024 revenue from automotive applications per Henkel Annual Report 2024, and Sika AG expanding its automotive and industrial adhesive and sealant content per vehicle in China, Japan, and India through 2024 as confirmed in its full-year 2024 results. OICA confirmed global passenger vehicle production of approximately 92 million units in 2024, with each conventional ICE platform consuming approximately 15 to 20 kilograms of adhesives and sealants across body-in-white structural bonding, windshield glazing, powertrain sealing, and interior trim assembly. EV platforms require substantially higher adhesive content than ICE equivalents, with battery module assembly consuming thermally conductive adhesive gap filler at 800 to 1,200 grams per cell module, structural battery pack bonding at 1.5 to 3.0 kilograms per vehicle, and copper bus bar isolation at 200 to 400 grams per vehicle, contributing an incremental 5 to 8 kilograms of reactive adhesive demand per EV above ICE baseline consumption. Dow announced a USD 40 million investment in China in August 2023 to enhance its automotive adhesives and sealants production capacity, increasing Chinese capacity by 20% and targeting EV platform assembly demand from BYD and SAIC. For instance, in Q4 2024, Sika AG, Switzerland, opened a new adhesives and sealants manufacturing facility in Pune, India, targeting the Indian automotive OEM market including Maruti Suzuki, Tata Motors, and Mahindra with localised production of structural bonding and glazing adhesives, reducing import lead times and supporting Sika's strategy to expand content per vehicle in Asian automotive markets. These are some of the key factors driving revenue growth of the market.

Henkel Adhesive Technologies Mobility and Electronics business area, accounting for approximately 36% of the EUR 11 Billion adhesive technologies segment revenue in 2024, includes automotive structural bonding, EV battery thermal management adhesives, powertrain sealing, and body shop hem flange adhesives across its LOCTITE and TEROSON product lines. Sika confirmed in its 2024 annual results that the automotive and industrial adhesive business declined in Europe on lower new vehicle demand while continuing to increase content per vehicle in China and India where EV production growth offset ICE volume softness. H.B. Fuller disclosed automotive adhesive revenue growth driven by structural adhesives for EV battery assembly in its FY2024 earnings, with the company supplying reactive hot melt and two-component epoxy adhesives to North American and Asian EV battery tier-one suppliers. 3M supplies automotive structural adhesive tapes and window bonding adhesives including its VHB tape product family to European body shop assembly lines, with automotive transportation consuming a significant share of its safety and industrial segment revenue.

However, automotive adhesive and sealant formulations using isocyanate-based polyurethane chemistry face REACH Annex XVII restriction requirements for diisocyanate professional use training from February 2023, adding compliance cost to one-component and two-component polyurethane adhesive production at European body shop applications where PU adhesives dominate window bonding and hem flange applications. European automotive production remained below 2019 peak levels in 2024 per OICA data, with German vehicle production declining materially in a challenging demand environment that Henkel identified in its 2024 annual report as weighing on the Adhesive Technologies Mobility segment despite above-market organic growth. The US-Iran conflict and the Strait of Hormuz supply disruption confirmed by the IMF in March 2026 has elevated MDI isocyanate feedstock costs at European polyurethane adhesive producers through methylene diphenyl diisocyanate upstream naphtha cost elevation, adding approximately USD 60 to USD 90 per metric tonne to reactive PU adhesive production cost in Q2 2026. These factors substantially limit automotive adhesives and sealants market growth over the forecast period.

Industry Trends & Market Dynamics

Drivers, Restraints and Market Dynamics

Battery electric vehicle architectures require thermally conductive gap filler adhesive between battery cells and cooling plates, structural potting adhesive to encapsulate cell arrays within module housings, and sealing adhesive at battery pack perimeter joints where ingress protection ratings of IP67 or IP68 require continuous bead-applied silicone or polyurethane sealant. Henkel confirmed in its 2024 Annual Report that the e-mobility segment represented 20% of its automotive adhesive and sealant sales and that it opened a battery testing centre at its Dusseldorf headquarters in 2024, directly connected to its global innovation centre, to expand EV adhesive development capabilities. CATL disclosed approximately 700 gigawatt-hours of annual battery production capacity in its 2024 annual report, and at 500 to 800 kilograms of thermally conductive adhesive per gigawatt-hour of module assembly, CATL alone is consuming an estimated 350,000 to 560,000 metric tonnes per year of battery assembly adhesive across its global network. Sika's investment in EV-specific structural adhesive and thermal management material product lines positions it to capture content-per-vehicle increases at Chinese domestic OEMs including BYD and NIO that are rapidly expanding EV production. Lightweighting Multi-Material Body Structure Bonding Driving Structural Adhesive Demand Multi-material automotive body structures combining advanced high-strength steel, aluminium sheet, carbon fibre reinforced plastic, and glass fibre reinforced thermoplastic panels require structural adhesive to join dissimilar materials that cannot be spot welded without galvanic corrosion risk or thermal distortion. Dow's BETAFORCE structural adhesive range, BASF's structural adhesive systems for CFRP-steel hybrid bonding, and Henkel's TEROSON structural adhesive for aluminium-intensive vehicle body structures each address the multi-material BIW requirement. The European Automobile Manufacturers Association ACEA confirmed European car production of approximately 11.1 million units in 2024, with premium segment vehicles at BMW Group, Mercedes-Benz, and Stellantis Premium Brands incorporating multi-material BIW structures that require 8 to 12 kilograms of structural adhesive per vehicle.

EU Commission Regulation on diisocyanates under REACH Article 68 requires industrial and professional users of isocyanate-containing adhesives and sealants to complete formal training programmes from 24 February 2023, with non-compliance potentially restricting supply in the European market for one-component PU body seam sealers and two-component PU structural bonding adhesives that dominate European BIW and glazing applications. European automotive OEM production softness in 2024, specifically in Germany where Henkel identified market challenges in its 2024 Annual Report, constrained adhesive volume growth in the region with the highest per-vehicle structural bonding adhesive content globally. The US-Iran conflict and the Strait of Hormuz supply disruption confirmed by the IMF in March 2026 elevated MDI feedstock costs at European polyurethane adhesive producers, with naphtha cost increases from Hormuz-restricted GCC exports adding approximately USD 60 to USD 90 per metric tonne to European reactive PU adhesive production cost in Q2 2026. These factors substantially limit automotive adhesives and sealants market growth over the forecast period.
