Henkel Addresses Supplier OEM Pain-points

- Aug 15, 2018-

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

  •  Liquid gasketing: Henkel offers a range of different gasketing technologies. Latest product innovations include Loctite AA 5820, which is suitable to provide a seal of multi-substrates or any flange design of e-drive housings. The polyacrylate adhesive shows 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 a 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 good oil resistance.

  •  PCB Technologies: Printed circuit board solutions include conformal coatings, thermal interface materials, low pressure moulding 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 Centres 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 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
