Henkel drives the future of e-Mobility

Henkel's portfolio of efficient, safe and sustainable solutions for the entire value chain of e-drives manufacturing is focused on six key application areas:

  • Liquid gasketing:
  • Henkel offers a wide range of different gasketing technologies. Latest product innovations include Loctite AA 5820, which is especially suitable to provide a reliable seal of multi-substrates or any flange design of e-drive housings. The polyacrylate adhesive shows excellent resistance to oils, including automatic transmission fluids (ATF), and can withstand temperatures from -40°C to +150°C.

  • Potting:
  • Another polyacrylate technology - Loctite AA 5831- is used for protection and fixation of parts in the e-motor or in the conversion electronic control unit. The compound has an ideal fit in large-series potting operations and cures within seconds under UV light and moisture.
    For e-drive stator coil potting applications, Henkel offers the two-component epoxy technology of Loctite PE 8082 which has a thermal conductivity of 1 W/mK, resulting in a significantly reduced working temperature. In addition, it shows outstanding oil resistance.

  • PCB Technologies:
  • Printed circuit board solutions include conformal coatings, thermal interface materials, low pressure molding products, and next generation of solder technologies for e-drive power conversion control units.

  • Impregnation Service:
  • Henkel's Loctite Impregnation Solutions (LIS) service leverages the flowability of low-viscosity polymeric resin to fill micro-porosities and voids ("leakers") and permanently seal components, such as aluminum cast e-drive housings, against common automotive fluids. The company operates 30 LIS Service Centers worldwide, which are fully certified to IATF 16949, ISO 14001 and OHSAS 18001.

  • Magnet bonding:
  • Loctite EA 9497 is used for the bonding of magnets inside the e-motor. The two-component epoxy adhesive has proven its long-term reliability in this application segment, combining a wide operating temperature range of -55°C to +200°C with high mechanical strength as well as good chemical and oil resistance. With its added thermal conductivity, it also supports a more efficient thermal management.

  • Parts Cleaners and Lubricants:
  • Henkel's range of machining products along with parts cleaners help to maintain a cleaner part through the entire process to ensure tight tolerances and reduce residues on parts, especially when used on sensitive e-drive modules


Henkel has a well-established reputation for its flexible capability of developing and tailoring specialized solutions to customer specifications. This is backed by technical test centers around the world and a strong focus on R&D and innovation. In addition, the company also maintains an extensive partner network for equipment, tools and engineering to serve a global OEM and Tier 1 customer base. The complete line of Henkel’s adhesive solutions for the design and large-series production of next-generation automotive electrical drive systems underscores the company’s commitment to anticipate the needs its customers for electrification.
