亞太地區汽車黏合劑和密封劑市場的趨勢和洞察。

OEM廠商朝向多材料白車身設計方向發展的趨勢

該地區的汽車製造商正將鋼、鋁、鎂和碳纖維增強塑膠整合到單一結構中，以減輕車輛總重8%至12%。這項改變使每輛車使用的黏合劑用量從約15公斤增加到超過25公斤。安賽樂米塔爾為其中國轎車採用的多階段整合工藝，結合了超高高抗張強度鋼和鋁製車門面板，這種組合由於存在電流腐蝕的風險，不適用於電阻點焊。 2025年，Ceres公司指定了一種環氧結構性黏著劑，該黏合劑無需表面預處理即可在鎂合金壓鑄副車架上實現超過10兆帕（MPa）的搭接剪切強度。據日本一級供應商稱，室溫固化的矽烷改質聚合物密封劑無需燒結爐，因此可以縮短生產週期。這些進步進一步鞏固了黏合劑在計畫於2027年至2030年間推出的大量生產平台上的應用。

基於中國VI和CAFE標準的輕量化要求

2026年1月，中國將實施「國六B」排放標準，屆時顆粒物排放限值將降低30%，氮氧化物（NOx）排放限值將降低50%，並透過引入實際道路排放氣體測試來加強法規執行力道。此外，汽車製造商（OEM）必須在2030年實現平均百公里油耗3.3公升的目標，這促使他們用黏合劑鋁材和複合材料取代鋼材，因此無需耗能的高能耗熱處理製程。現代和起亞也採用了類似的方法，在後行李箱蓋和引擎蓋中使用反應型熱熔膠，使每個開啟和關閉部分的重量減輕3至5公斤。隨著日本第四階段排放標準於2026年生效，減重要求將擴展到廂型車和輕型卡車，這將增加供應商對經認證的單組分聚氨酯的需求。

異氰酸酯和環氧樹脂原料價格波動

2025年全年，二苯基甲烷二異氰酸酯（MDI）供應意外中斷以及原油價格波動導致現貨市場劇烈波動，使得東協地區小規模複合材料生產商的利潤率下降了200-300個基點。 2026年初，環氧樹脂市場疲軟，迫使一些供應商延後研發和產能擴張計畫。 DIC公司位於千葉縣的新環氧樹脂工廠獲得了津貼以確保國內供應，這凸顯了為應對原料風險而進行大量資本投資的必要性。雖然矽烷改質聚合物替代品有助於減少對異氰酸酯的依賴，但由於其在120 度C以上溫度下會發生熱老化，因此應用仍然有限。

細分市場分析

聚氨酯具有400%的延伸率和濕氣固化特性，適用於黏合不同基材，預計到2025年將佔據亞太地區汽車黏合劑和密封劑市場27.25%的佔有率。漢高公司的導熱聚氨酯產品導熱係數為1.2至3.4瓦/米·開爾文（W/m·K），廣泛用於電動車（EV）模組的黏合。環氧樹脂黏合劑適用於引擎室內等需要耐高溫達180 度C的應用，而介電強度超過10千伏/毫米（kV/mm）的矽酮黏合劑則較適用於高壓電池組。

醋酸乙烯酯/乙烯/乙烯-醋酸乙烯酯 (VAE/EVA) 水性系統目前市佔率較小，但預計到 2031 年將以 6.55% 的複合年成長率成長。其成本績效效益高，且符合揮發性有機化合物 (VOC) 法規，因此適用於印度的車頂內襯和車門內裝板等應用。這些黏合劑有助於目的地設備製造商 (OEM) 滿足日本對汽車內裝甲醛濃度的最高限值（100 微克/立方米，µg/m³），而無需投資紫外線 (UV) 燈。在國內供應商區域產能提升的推動下，VAE/EVA黏合劑市場預計將顯著擴張。

Asia-Pacific Automotive Adhesives And Sealants Market Trends and Insights

OEM Preference for Multi-Material Body-in-White Designs

Automakers in the region are integrating steel, aluminum, magnesium, and carbon-fiber-reinforced polymers within single structures to reduce curb weight by 8-12%. This change has increased adhesive usage from approximately 15 kilograms to over 25 kilograms per vehicle. ArcelorMittal's multi-phase integration process for Chinese sedans combines ultra-high-strength steel with aluminum closures, a pairing unsuitable for resistance spot-welding due to the risk of galvanic corrosion. In 2025, Seres adopted magnesium die-cast subframes, specifying epoxy structural adhesives that achieve lap-shear strength exceeding 10 megapascals (MPa) without requiring surface pretreatment. Japanese tier-one suppliers report that silyl-modified-polymer sealants, which cure at ambient temperatures, reduce cycle times by eliminating the need for bake ovens. These advancements are embedding adhesives more deeply into high-volume platforms scheduled for launch between 2027 and 2030.

Weight-Reduction Mandates Under China VI and CAFE Norms

China's implementation of China VI B standards in January 2026 will reduce particulate matter thresholds by 30% and nitrogen oxide (NOx) limits by 50%, while real-driving-emissions testing will enhance enforcement. Additionally, original equipment manufacturers (OEMs) must achieve a fleet average of 3.3 liters per 100 kilometers (L/100 km) by 2030, driving the substitution of steel with adhesive-bonded aluminum and composites that eliminate the need for energy-intensive heat tunnels. Hyundai and Kia are following a similar approach, using reactive hot-melts on tailgates and hoods to reduce weight by 3-5 kilograms per closure. Japan's Stage 4 regulations, effective in 2026, extend lightweighting requirements to vans and mini-trucks, increasing supplier demand for qualified one-component polyurethanes.

Volatility in Isocyanate and Epoxy Feedstock Prices

Unplanned methylene diphenyl diisocyanate (MDI) outages and fluctuations in crude oil prices caused spot-market variations through 2025, reducing the margins of smaller ASEAN formulators by 200-300 basis points. The epoxy market weakened in early 2026, leading some suppliers to delay research and development initiatives and capacity expansion plans. DIC's new Chiba epoxy unit, subsidized to ensure domestic supply, highlights the significant capital investment required to manage raw material risks. While silyl-modified polymer alternatives help reduce isocyanate exposure, they remain limited by thermal-aging constraints above 120°C.

Other drivers and restraints analyzed in the detailed report include:

1. Uptick in EV Battery-Pack Gasketing Demand
2. Start-Ups Commercializing Bio-Based Polyurethane Chemistries
3. OEM Push Toward Mechanical Fastening for Ease of Repair

Segment Analysis

Polyurethane is expected to account for 27.25% of the Asia-Pacific Automotive Adhesives & Sealants market share in 2025, driven by its 400% elongation and moisture-curing properties, which are suitable for mixed-substrate joints. Henkel's thermal-conductive polyurethane grades, offering thermal conductivity of 1.2-3.4 watts per meter-kelvin (W/m*K), are widely used in bonding electric vehicle (EV) modules. Epoxy adhesives are utilized in under-hood applications requiring resistance to temperatures up to 180°C, while silicone adhesives are preferred for high-voltage battery packs due to their dielectric strength exceeding 10 kilovolts per millimeter (kV/mm).

Vinyl acetate ethylene/ethylene vinyl acetate (VAE/EVA) water-borne systems, though currently smaller in market share, are projected to grow at a compound annual growth rate (CAGR) of 6.55% through 2031. Their cost-effectiveness and compliance with volatile organic compound (VOC) regulations make them suitable for applications such as headliners and door panels in India. These adhesives help original equipment manufacturers (OEMs) meet Japan's in-cabin formaldehyde limit of 100 micrograms per cubic meter (µg/m3) without requiring ultraviolet (UV) lamp investments. The market for VAE/EVA adhesives is expected to expand significantly, supported by increased regional production capacity from domestic suppliers.
