Automotive Adhesives and Sealants Industry Analysis and Growth Forecast to 2030

The automotive adhesives and sealants are widely used in smaller to large-sized devices, such as sensors, and vehicle chassis. Numerous high-performing cars are produced with lightweight composite materials to keep the weight minimal. The composite materials, coupled with the mechanical fasteners facilitate welding and keep the weight lighter.

Structural adhesives are highly preferred by professionals as they can create a bond and join different types of materials. The structural adhesives offer rubber toughening that facilitates the absorption of vibration and impact forces.

The automotive adhesives and sealants industry is projected to reach $11,643.5 in 2030. The electronic systems inside the car utilize types of adhesives, it includes switches and relays, sensors, sealing and potting electrical components, and bonding electric motors.

Epoxy Adhesives

Epoxy adhesives offer good adhesion on various substrates, and have very low curing shrinkage. They are highly suitable for bonding metals, ceramics, concrete, wood, and various plastics. Cured epoxy resin chemical structure is strong and rigidly cross-linked to facilitate structural bonding applications. Numerous epoxy adhesives have been commercialized, by combining epoxy resins and various curing agents.

Acrylic Adhesives

The acrylic adhesives are highly replacing the traditional bonding methods such as rivets, welts, and brazing in the automotive industry. They perform great in the bonding of steel, aluminum, and other composite materials. Acrylic adhesives are utilized in the exterior vehicle components bonding, such as framework and door panels. These components are usually subjected to high stress and impact on a regular basis. The acrylic adhesives provide durable and flexible join enabling them to withstand pressure. In addition, acrylic adhesives enhance aesthetics and minimize the manufacturing cost of vehicles.

Silicone Adhesives

Silicone adhesives are standout in ensuring lifelong protection to vehicles from environmental causes, as they have inherent stress-reducing mechanical flexibility and chemical stability. Silicon-oxygen bonds in silicone-based adhesives possess similarities to that of glass, and it remains durable against harsh environmental stress, such as extreme temperature, cycling, water immersion, changes in humidity levels, and UV exposure.

Silicone solutions retain elasticity and flexibility under challenging conditions, relieve interfacial stresses, and facilitate small joint movements that further prevent joint fatigue and enhance the service life of the vehicle. Moreover, silicone adhesives are formulated to mitigate the feat from circuit boards by incorporating thermally conductive additives.

Therefore, adhesives and sealants pose a great role in the automotive industry as they increase the service life of the vehicle, along with reducing the weight.
