Toagosei America is a global leader in chemical innovations, recognized for iconic brands like Aron Alpha and a comprehensive portfolio of industrial adhesives, coatings, and specialty polymers and oligomers. As automotive engineering shifts toward lightweighting and electrification, manufacturers are increasingly replacing mechanical fasteners with advanced chemical bonding solutions that offer superior durability and reduced vehicle weight. From electric vehicle (EV) battery systems to high-end interior finishes, Toagosei America provides the specialized materials required for modern automotive manufacturing.

Supporting Electrification: Battery and Fuel Cell Materials

Toagosei offers specialized solutions for both fuel cell vehicles (FCVs) and lithium-ion battery (LiB) systems. These materials are engineered to withstand rigorous chemical environments while optimizing production efficiency.

Fuel Cell Vehicle (FCV) Solutions

For fuel cell separator bonding, Toagosei provides special modified polyolefin-type hot melt adhesives that offer excellent chemical resistance, excellent bonding durability, and long-term gas sealing. Additionally, our acrylate-based UV/LED curable adhesives are used for laminating internal cell components. These adhesives enable bonding in seconds and suppress catalyst poisoning components while offering good screen printability. 

Lithium-Ion Battery (LiB) Components

Toagosei supports LiB production with the following materials:

  • Ethylene Carbonate. A highly polar organic solvent used in LiB electrolytes, available in refined grades with 99.9%+ purity, as well as general-purpose grades. 
  • Acrylic-Based Binders. Designed for LiB anodes, these binders maintain conductive pathways for electron flow between active materials and current collectors, contributing to extended battery life.

Interior & Exterior Component Solutions

Toagosei materials enhance vehicle comfort, aesthetics, and resistance to environmental stressors.

Interior Comfort and Aesthetics

Our adhesives and additives prioritize both bond strength and passenger well-being:

  • Fabric and Board Adhesives. ARON MELT® and ARON TUCK® adhesives provide reliable bonding for ceilings, carpets, and decorative interior films.
  • Air Quality and Safety Products. Our AlleRemove treatment agent reduces allergens from dust mites and pollen in seat covers and headliners. We also offer KESMON, a chemical adsorbent deodorant that can be used in cabin filters to provide volatile organic compound (VOC) control for a cleaner cabin environment.

Exterior Durability

For exterior automotive applications, our industrial adhesives and coatings resist weathering and corrosion:

  • Adhesives for Window and Door Components. ARON MIGHTY® and Aron Alpha® are utilized for window and door moldings to ensure long-term adhesion against outdoor hazards.
  • Wiper Blade Coatings. ARON POWDER® is a top-market-share powder coating for wiper blades, providing a matte finish with exceptional weather and corrosion resistance.

Electronics, Displays, and Sensor Technologies

As vehicles become more autonomous and connected, the precision of electronic assemblies is paramount. Toagosei provides adhesives, resins, and coating formulation for use in the following applications: 

  • In-Vehicle Displays. Our low-viscosity, solvent-free UV adhesives (ARONIX®) bond to glass, PET, and PC while maintaining excellent transparency for optical clarity.
  • Camera Modules. Our UV adhesives allow for precision fixing with a low curing shrinkage rate of 2.5%, which minimizes positional displacement during assembly.
  • LiDAR Systems. We offer a glass-replacement resin for LiDAR covers that provides 90% transmission of near-infrared light while completely cutting visible light.
  • Electrode Terminals and Circuit Board Protection. Our moisture-proof insulation coatings protect electrode terminals and circuit boards, maintaining high insulation performance under extreme humidity. 

Coatings and Sealants for Durability and Protection

Toagosei coatings and sealants are engineered for areas exposed to harsh fluids and high temperatures. We provide a variety of solutions to ensure the longevity of critical components: 

  • Waterproof Sealants for Wire Harnesses (Aron Alpha®). This sealant penetrates and cures within gaps between copper wires, providing protection against impacts and meeting rigorous insulation and airtightness standards.
  • Oil-Resistant Sealants for Oil Filters (ARONIX®). This solvent-free material maintains its hardness even after immersion in 140 °C hot oil, ensuring long-term performance without VOC emissions.
  • Scratch-Resistant Coating for Lamps (ARONIX®). This coating formulation protects headlight surfaces from yellowing and degradation caused by UV exposure while maintaining transparency and irradiation performance.
  • Weather-Resistant Powder Coating for Wiper Blades (ARON POWDER®). This matte-finish coating offers excellent edge coverage and corrosion resistance for outdoor automotive components, such as wiper blades. 

Specialty Polymers and Elastomers for Structural and Sealing Applications

Toagosei offers a specialized range of thermoplastic elastomers (TPE) and resins designed to replace traditional rubber in structural and sealing roles. Our solutions include:

  • Thermoplastic Elastomers for Door Trims, Window Frames, and Seals. The AROSTOMER TF and AR-1000 series provide excellent weather resistance for quarter window frames and antenna packings, while our soft-grade polyester elastomers are proven for use in door trims and side visor seals.
  • Anti-Vibration Materials. Specialized TPE grades with low resilience and excellent vibration damping are utilized in anti-vibration clamps to reduce mechanical noise and wear.
  • Heat-Resistant Elastomers for Engine Components. Our high-heat-resistance grade elastomers exhibit excellent compression set characteristics and oil resistance, making them ideal substitutes for rubber in applications such as starter motor packings and brake fluid tank caps.
