Body in White
Bonding and Sealing Technologies for Automotive Body Assembly
Body in White is the stage of vehicle manufacturing where the core body structure is assembled before paint, trim, powertrain, and final assembly. As automakers work with lighter materials, mixed substrates, and more complex body designs, adhesives and sealants can help support structural bonding, seam sealing, corrosion protection, and assembly flexibility.
H.B. Fuller works with automotive manufacturers and suppliers to evaluate adhesive and sealant technologies for Body in White applications based on substrates, production processes, application methods, and performance requirements.
Supporting Modern Body Structure Design
Automotive body structures are changing as manufacturers balance lightweight design, durability, material compatibility, and production efficiency. Adhesive and sealant technologies can support selected applications where traditional joining methods may need to be supplemented.
H.B. Fuller solutions can help support:
- Bonding of metals, composites, plastics, and mixed-material assemblies
- Structural and panel bonding
- Seam sealing and joint protection
- Corrosion protection in exposed or vulnerable areas
- Sound damping and vibration-related needs
- Lightweight vehicle design and process flexibility
Product selection should be validated for each application based on substrate, equipment, cure profile, process conditions, and end-use requirements.
Body in White Applications
Structural and Panel Bonding
Structural and panel bonding adhesives can help join vehicle body components while supporting design flexibility and mixed-material assembly. These technologies may be used where manufacturers need durable bonds across automotive substrates.
Seam Sealing and Joint Protection
Seam sealants help close gaps, protect joints, and support long-term body durability. Depending on the application, sealants may be selected for flexibility, weather resistance, corrosion protection, paint process compatibility, or application efficiency.
Sound Damping and Underbody Protection
Vehicle body design can influence noise, vibration, harshness, and exposure to road conditions. H.B. Fuller offers transportation solutions used for sound damping, underbody protection, and corrosion-resistance applications.
Adhesive and Sealant Technologies
Depending on the Body in White application, H.B. Fuller may recommend technologies such as polyurethane adhesives and sealants, silane-modified polymers, epoxies, modified acrylics, MMA adhesives, water-based coatings, butyl materials, or tape-based sealing solutions.
Our technical experts help evaluate the right option based on bond strength, flexibility, open time, cure speed, substrate compatibility, and manufacturing requirements.
