Automotive Adhesives and Sealants

Automotive Adhesives and Sealants

Automotive adhesives and sealants are used to bond different materials in vehicle manufacturing. They are also used to repair damaged or worn-out parts.

MMA (methyl methacrylate) adhesives have the highest market share based on resin type. They are widely used for BIW applications as they help reduce vehicle weight, thereby saving fuel consumption.


Automotive manufacturers are increasingly focusing on lightweighting their vehicles to meet customer demand and regulatory requirements. Lightweighting reduces the overall vehicle weight to improve fuel efficiency and performance, without compromising on passenger safety and comfort. In addition to this, it also helps in achieving aesthetics that appeal to customers and meets design standards. For example, using adhesives to bond materials instead of welding or joints eliminates stress concentrations and protruding fasteners and allows for a smooth surface finish that is preferred by designers and consumers alike.

Structural adhesives provide strength and rigidity to components, allowing them to be lighter than conventional metal fasteners. They also work well on non-traditional materials such as aluminium and composites, which cannot be welded. Moreover, these types of adhesives can be dispensed and cured directly on components to form integrated gaskets. These benefits make them a popular choice for reducing the overall weight of the vehicle.

Several major players in the industry are investing in research and development to develop future products with enhanced attributes for use in the auto sector. They are experimenting with different resins, fillers and additives to develop high-performance adhesives that can withstand temperature extremes and harsh chemicals. These developments will help them stay competitive in the market. Asia Pacific is expected to be the largest market for automotive adhesives and sealants. This is mainly due to the region’s booming automotive production and increasing consumer purchasing power.


As an alternative to mechanical fasteners, automotive adhesives and sealants offer advantages such as a lighter component weight and a cleaner, more streamlined finish. They can also help with stress distribution and improve the performance of components. In addition, they can be used with a wider variety of materials than traditional mechanical fasteners. This can increase manufacturer choice and allow for better design flexibility.

As manufacturers look to reduce vehicle weight, the demand for automotive adhesives and sealants is growing. These products are increasingly being used in vehicle assembly applications and in the body-in-white (BIW) process, where they can reduce a car’s overall weight while offering a high level of durability. This is especially important as manufacturers strive to meet stringent environmental regulations.

Automotive adhesives and sealants can be automotive adhesives and sealants divided into one-part, two-part, anaerobic, heat-cure, hot-melt, and silicone products based on their cure type. They can also be categorized by resin, such as polyurethane, epoxy, and acrylic. These products are used in many applications throughout a vehicle, including the interior, exterior, under the hood, and other areas.

The COVID-19 pandemic may have set back the growth of this market, but it is expected to recover as automakers resume production and consumers focus on safety, lightweight vehicles, and sustainability. Moreover, the increasing demand for electric vehicles is likely to fuel the growth of this market.


Several manufacturers are introducing automotive adhesives and sealants that offer superior durability to help meet the industry’s growing demands for higher vehicle speeds and safety. Additionally, automotive adhesives and sealants help reduce noise levels to improve the driving experience for consumers.

Moreover, the global market for automotive adhesives and sealants is highly consolidated, with a handful of prominent regional and international players holding a significant share in the market. Some of these companies include Delo Industrial Adhesives, Arkema S.A, Henkel AG & Co. KGaA, H.B. automotive adhesives and sealants Fuller Company, 3M, Master Bond Inc., Heartland Adhesives LLC, Avery Dennison Corporation, Jowat SE, and ITW Performance Polymers.

The demand for automotive adhesives and sealants is expected to increase significantly in North America and Europe, owing to the region’s huge vehicle production capacity. Moreover, strict environmental regulations and the increasing focus on fuel efficiency and carbon emissions are also boosting the demand for automotive adhesives and sealants.

The Asia-Pacific market is gaining traction due to the country’s booming automotive manufacturing sector and growing consumer purchasing power. Furthermore, the increasing adoption of electric vehicles is expected to create opportunities for automotive adhesives and sealants in the region. MMAs and other methyl methacrylate-based adhesives are the most widely used automotive adhesives in the Asia-Pacific market. These automotive adhesives are ideal for plastic roof bonding, automobile hose bonding, and heat exchanger sealing as well as for attaching electrical components such as switches, relays, and sensors.


In addition to structural strength and durability, automotive adhesives are used to dampen noise, vibrations, and shocks for the safety of occupants. They are also used to bond the wire harness, windshield, and other components of the vehicle, as well as to seal fuel tanks and oil pumps. They are made to withstand exposure to chemicals, fuels, and other fluids and are often resistant to heat and impact.

Automobile manufacturers are increasingly relying on adhesives to replace welding and mechanical fasteners, as they are more efficient and cost-effective. They are using these materials to reduce the weight of vehicles, improve fuel efficiency, and comply with strict environmental regulations. Additionally, these adhesives can be applied on surfaces that are not accessible for welding and can be cured in a short timeframe.

VAE/EVA resin-based automotive adhesives and sealants are expected to dominate the market due to their utility as high-performance, durable, and weather-resistant bonds. These are ideal for a wide range of applications, such as seat and interior assembly, automobile electronic components fixation, and exterior trim applications.

Other resin-based automotive adhesives and sealants held the second largest share in 2021, owing to their excellent adhesion properties to a variety of substrates. These include styrene acrylate, polyurethane, silicone, and methyl methacrylate (MMA). MMAs are popular among consumers, as they provide the versatility of a structural adhesive with a high-cure rate.
