Market Data
The global automotive sealants market size was USD 8.62 Billion in 2025 and is expected to register a revenue CAGR of 6.2% during the forecast period. Market revenue growth is supported by EV battery enclosure sealing demand from CATL, BYD, Toyota, and Volkswagen battery platforms requiring thermally conductive silicone and PU sealants with electrical insulation resistance and electrolyte chemical compatibility at IP67 water ingress protection specifications that command USD 28 to USD 46 per kilogram versus USD 6 to USD 12 per kilogram for conventional body-in-white seam sealants, Henkel LOCTITE SI 5950 silicone sealant availability for electric vehicles confirmed in August 2023, and Sika's Q4 2024 opening of a new adhesives and sealants manufacturing facility in Pune, India. Henkel AG reported its Adhesive Technologies division generated revenues of EUR 11.3 Billion in fiscal year 2024, with automotive sealants within its transportation adhesive and sealant category contributing as one of the highest-growth product lines on EV battery enclosure and lightweight body structure bonding demand. Sika AG reported record total revenues of CHF 11.76 Billion in fiscal year 2024 across its construction and industry segments, with its automotive sealant and adhesive business serving OEM body-in-white, glazing, and battery enclosure applications growing at above-plan rates in China and Europe on EV platform production ramp-up at BYD, SAIC, and Stellantis programmes. For instance, in Q1 2025, Henkel, Germany, announced a strategic partnership with a leading Chinese electric vehicle manufacturer to co-develop advanced adhesives and sealants for battery pack and lightweight structure applications, confirming Henkel's position as the primary EV-specific sealant development partner for Chinese OEM programmes. These are some of the key factors driving revenue growth of the market.
Silicone sealants account for approximately 34% to 38% of global automotive sealant revenue by product type, anchored by their use in automotive glazing bonding and sealing at windscreen and rear window installations and the growing EV battery enclosure application where Henkel LOCTITE SI 5950 and Dow SYLGARD silicone sealant formulations provide thermal cycling and electrical insulation performance that polyurethane and acrylic alternatives cannot achieve within EV specification limits. Polyurethane sealants represent the second-largest product segment at approximately 28% to 32% of total automotive sealant revenue, with reactive two-component PU systems from Sika, Bostik, and Dow used in direct glazing applications at OEM windscreen installation facilities. 3M launched a new range of automotive seam sealants in July 2024 targeting both OEM production body shops and refinish body shop applications, expanding its automotive sealant portfolio. Avery Dennison Corporation entered a partnership with Yiannimize in February 2025 for developing new automotive sealant ranges for North American consumers.
However, EV platform body architecture uses greater proportions of structural adhesive bonded aluminium and carbon fibre composite panels that reduce the number of body seam sealant application points below the equivalent ICE vehicle body manufacturing process. Automotive sealant production cost is affected by silicone monomer and polyurethane isocyanate feedstock cost volatility, with the Strait of Hormuz supply disruption confirmed by the IMF in March 2026 elevating methanol and isocyanate precursor costs at European silicone sealant and PU sealant manufacturers, adding approximately USD 140 to USD 240 per metric tonne to automotive sealant active material cost in Q2 2026. These factors substantially limit automotive sealants market growth over the forecast period.
Industry Trends & Market Dynamics
Drivers, Restraints and Market Dynamics
EV battery pack enclosure sealing requires sealant performance specifications including electrical insulation resistance above 10 megaohms at 500 volts DC to prevent battery short-circuit through the sealant layer, thermal stability from minus 40 degrees Celsius to plus 180 degrees Celsius through battery thermal cycling, and electrolyte chemical resistance to lithium salt electrolyte formulations that degrade conventional acrylic and butyl sealants. Henkel's LOCTITE SI 5950 silicone sealant for EV applications, commercially available from August 2023, was specifically formulated to provide heat resistance, chemical resistance, vibration damping, and adhesion to aluminium housing and glass lid battery module substrates. Each BEV requires approximately 40 to 120 metres of battery enclosure perimeter sealant application at USD 28 to USD 46 per kilogram, generating USD 1,200 to USD 5,400 per vehicle of EV battery sealant content versus USD 80 to USD 160 per vehicle of conventional body-in-white seam sealant at OEM production rates. Sika's strategic partnership with ElringKlinger in Q3 2024 to co-develop high-performance gasket and sealant systems for electric powertrains combines Sika specialty sealant chemistry with ElringKlinger powertrain engineering for multi-material battery housing substrate compatibility. Sika India Expansion and Asia-Pacific OEM Production Growth Driving Automotive Sealant Volume Sika AG opened a new adhesives and sealants manufacturing facility in Pune, India in Q4 2024 to produce automotive sealants and adhesives for the rapidly growing Indian vehicle production market, where OICA confirmed Indian passenger vehicle production of approximately 5.8 million units in 2024 at a growth rate of approximately 8% year over year. Chinese OEM production expansion at BYD, SAIC, Geely, and Changan is driving EV-specific battery enclosure sealant demand in Asia-Pacific, with Henkel's Q1 2025 strategic partnership with a Chinese EV manufacturer for co-development of EV battery and lightweight structure sealants confirming the Chinese EV OEM market as the primary growth driver for Henkel's automotive sealant business in Asia-Pacific through 2028.
Electric vehicle body-in-white construction incorporates greater proportions of structural adhesive bonded aluminium multi-material panels that reduce the number of spot-weld flanges and body seam joints requiring sealant application compared to conventional all-steel ICE vehicle body construction, as structural adhesive bonding replaces the weld-flange seam sealant application that generates the majority of body-in-white seam sealant volume at conventional ICE production facilities. The structural adhesive displacement of seam sealant application points is estimated to reduce body-in-white seam sealant consumption by approximately 15% to 25% per EV platform versus equivalent ICE platform. Polyurethane isocyanate and silicone methanol feedstock cost elevation from the Strait of Hormuz supply disruption confirmed by the IMF in March 2026 has added approximately USD 140 to USD 240 per metric tonne to automotive sealant raw material cost at European Henkel and Sika production facilities. These factors substantially limit automotive sealants market growth over the forecast period.

Strategic Developments
Analyst Review
The IMF confirmed in March 2026 that the closure of the Strait of Hormuz had disrupted approximately 20% of global oil and seaborne LNG flows following escalation of the US-Iran conflict. For the automotive sealants market, the Hormuz disruption operates through two feedstock cost pathways. The primary pathway is polyurethane isocyanate cost elevation at European PU sealant producers: MDI and TDI isocyanate production in Saudi Arabia and UAE is exported through Hormuz transit routes to European and Asian automotive PU sealant manufacturers including Henkel at Dusseldorf and Sika at Zurzach, adding approximately USD 140 to USD 240 per metric tonne to European automotive PU and epoxy sealant raw material cost in Q2 2026. The secondary pathway is silicone monomer methanol cost elevation at silicone sealant producers, as methanol feedstock from GCC chemical plants to Shin-Etsu Chemical and Dow silicone monomer production has been partially disrupted, adding approximately USD 80 to USD 140 per metric tonne to EV battery enclosure silicone sealant compound cost.
