Henkel, a specialist in adhesives and sealants, has introduced three new products to its range of potting adhesives designed for specific challenges in the automotive industry. These potting products are tailored to protect sensitive electronic components such as ECU connectors, sensors, and e-motors from moisture and exposure to automotive fluids. They are engineered for seamless integration into existing manufacturing processes and optimal compatibility with materials used in automotive applications.
One of the new products, Loctite SI 5035, is a one-part silicone potting sealant that offers corrosion-free potting for components like ECU connectors. It provides deep light cure capability, combining ultraviolet and visible light with a secondary moisture cure mechanism for shadow curing. The sealant forms a medium-strength, flexible rubber seal that can withstand high-pressure testing immediately after UV curing, eliminating the need for energy-intensive ovens. The fast depth of cure reduces the need for staging parts, thus reducing the process footprint on the plant floor.
Another new product, Loctite AA 5832, is a dual-cure (UV/moisture) polyacrylate potting sealant designed for high performance in sealing against transmission fluids and oil. This low-viscosity material is used for potting and sealing components like ECU connectors and mechatronics, increasing their reliability in harsh automotive environments. Cured via UV light, this product enables lower energy consumption, making it more sustainable for manufacturing processes.
Loctite PE 8086 AB is a thermally-conductive potting material specially designed for encapsulating and protecting components such as motor stators, actuators, transformer coils, and transmission actuators from thermal shock. This two-component epoxy material offers high thermal conductivity, low viscosity for easy processing, excellent electrical insulation, and resistance to automatic transmission fluid. It maintains optimal operating temperatures and protects components from environmental factors, contaminants, and mechanical stress. As a solvent-free product, it produces no VOCs during the curing process, making it more environmentally friendly.
Arthur Ackermann, Business Development Manager at Henkel, stated that the company is committed to meeting the evolving challenges of automotive electronics with a comprehensive range of potting solutions. The new products have been developed in collaboration with customers and partners to exceed industry expectations, enabling high-efficiency manufacturing and ensuring the durability and dependability of components throughout the vehicle’s lifecycle. Henkel’s expertise and innovation capabilities have led to the creation of products that offer high accuracy, sustainability, and longevity in the automotive industry.
Overall, Henkel’s new potting adhesives offer solutions for protecting sensitive electronic components in automotive applications. These products are designed to integrate seamlessly into manufacturing processes, providing efficient encapsulation and protection for components exposed to harsh conditions. With a focus on innovation, sustainability, and durability, Henkel is at the forefront of meeting industry challenges and exceeding customer expectations in the automotive electronics sector.
