Control Flow Seam Sealer Market Report 2026

The control flow seam sealer market size has grown strongly in recent years. It will grow from $1.04 billion in 2025 to $1.11 billion in 2026 at a compound annual growth rate (CAGR) of 7%. The growth in the historic period can be attributed to automotive body corrosion prevention needs, growth in vehicle production volumes, expansion of industrial assembly lines, demand for structural reinforcement, adoption of seam sealing in manufacturing.

The control flow seam sealer market size is expected to see strong growth in the next few years. It will grow to $1.44 billion in 2030 at a compound annual growth rate (CAGR) of 6.7%. The growth in the forecast period can be attributed to electric vehicle body manufacturing growth, demand for low voc sealants, automation in automotive plants, advanced material compatibility requirements, expansion of aerospace applications. Major trends in the forecast period include increasing adoption of automated sealing applications, rising demand for corrosion resistant sealants, shift toward lightweight vehicle assembly, growth in high precision body sealing, rising use of single component sealers.

The rising production of vehicles is anticipated to drive the growth of the control flow seam sealer market. Vehicles serve as transport systems designed to carry passengers or cargo between locations. Increasing urbanization is leading to higher vehicle ownership as city populations expand and demand for transportation grows. Control flow seam sealers are essential in vehicle manufacturing, as they seal seams to block moisture, air, and dust, thereby preventing corrosion. They also contribute to structural integrity and reduce noise, enhancing long-term durability and performance. For example, in March 2024, the European Automobile Manufacturers Association (ACEA) reported that global car production reached nearly 76 million units, a 10.2% increase from the previous year. European car production also saw significant growth, reaching nearly 15 million units with a 12.6% year-on-year rise. As a result, the surge in vehicle production is fueling the growth of the control flow seam sealer market.

The expansion of the aerospace industry is projected to support the growth of the control flow seam sealer market. The aerospace industry encompasses the design, manufacturing, and development of aircraft, spacecraft, and associated systems for both commercial and military applications. This sector is growing due to increased global defense expenditures and demand for advanced technologies to reinforce military strength. In aerospace applications, control flow seam sealers are used to ensure precise and consistent joint sealing, improving structural integrity and preventing leakage. They enhance the durability of components, protect against environmental damage, and contribute to overall aircraft safety. For instance, in January 2024, the International Air Transport Association (IATA) reported a 36.9% increase in total air traffic in 2023 compared to 2022, based on revenue passenger kilometers (RPKs). International air traffic alone rose by 41.6% during the same period. Consequently, the growing aerospace industry is accelerating the demand for control flow seam sealers.

The increasing demand within the construction industry is expected to drive the growth of the control flow seam sealer market going forward. The construction industry encompasses the development and delivery of infrastructure, residential, commercial, and industrial projects from planning and design through completion. Its growth is being propelled by rising urbanization, which increases the need for housing and infrastructure to support expanding urban populations. Control flow seam sealers improve construction quality by sealing building joints against air, moisture, and dust, thereby enhancing energy efficiency and strengthening structural durability. For example, in February 2025, the U.S. Census Bureau, a U.S.-based government statistical agency, reported that construction spending in December 2024 reached a seasonally adjusted annual rate of $2.19 trillion, 4.3 percent higher than the December 2023 estimate of $2.1 trillion. Therefore, the increasing demand within the construction industry is supporting the growth of the control flow seam sealer market.
