Henkel releases new potting compounds for EV components

May 22, 2024

Henkel has expanded its portfolio of potting adhesives with three new products.

The new offerings include silicone-based Loctite SI 5035, polyacrylate-based Loctite AA 5832, and two-component-based Loctite PE 8086 AB.

Loctite SI 5035 is a one-part silicone potting sealant that provides corrosion-free potting to sensitive components such as ECU connectors. It offers the advantage of deep light cure capability, ultraviolet and visible, combined with a secondary moisture cure mechanism for shadow curing. The fast processing and excellent adhesion characteristics reduce the resource and space requirements on the manufacturing line.

Loctite AA 5832 is a dual cure (UV/moisture) polyacrylate potting sealant designed for high performance in sealing against automatic transmission fluids and oil. This one-component, low-viscosity material is used for potting and sealing various automotive and electronic components, increasing their reliability in harsh automotive environments.

Loctite PE 8086 AB is a thermally conductive potting material designed for encapsulation and protection of electronics components such as motor stators, actuators, transformer coils and transmission actuators from thermal shock. This two-component epoxy material offers high thermal conductivity, low mixed viscosity for easy processing, excellent electrical insulation at high and room temperatures, and Automatic Transmission Fluid (ATF) oil resistance.

Arthur Ackermann, Business Development Manager Auto Electronics North America at Henkel, said, “Utilizing our strong expertise and innovation capabilities, these new products have been developed in collaboration with our customers and partners to surpass industry expectations. They not only enable high efficiency, high-accuracy manufacturing but also ensure the durability, longevity, and dependability of components over the vehicle’s lifecycle.”
