Henkel is launching two new one-component potting sealants with silicone-based Loctite SI 5035 and polyacrylate-based Loctite AA 5832. The third new sealant solution is two-component based Loctite PE 8086 AB which combines thermal management with physical protection.
Seamless Integration into Manufacturing Process
These potting products are designed for seamless integration into the manufacturing process and optimal compatibility with the materials used in automotive applications. They enable more efficient encapsulation and protection of components.
“
As a manufacturer of adhesives, sealants, and functional coatings for the automotive industry, Henkel is meeting the evolving challenges of automotive electronics with a comprehensive range of potting solutions,” says Arthur Ackermann, business development manager auto electronics North America at Henkel. “
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.”
Loctite SI 5035 - Protection Against Common Moisture and Fluid Exposure
Loctite SI 5035 is a one-part silicone potting sealant that provides corrosion-free potting to sensitive components such as ECU connectors. As flowable sealant, it offers the advantage of deep light cure capability, ultraviolet and visible, combined with a secondary moisture cure mechanism for shadow curing.
Loctite SI 5035 forms a medium strength, flexible rubber sealant that can withstand high pressure testing immediately after UV curing. The fast processing and excellent adhesion characteristics reduce the resource and space requirements on the manufacturing line.
The UV cure system eliminates the need for energy intensive ovens common with typical heat cure systems. The fast depth of cure reduces the need for staging parts usually required with standard RTV silicones, significantly reducing process footprint on the plant floor.
Loctite AA 5832 - Shield Against Transmission Fluid and Oil
Loctite AA 5832 is a dual cure (UV/moisture) polyacrylate potting sealant that is 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 such as ECU connectors, mechatronics, ADAS components, which increases their reliability in harsh automotive environments.
Loctite AA 5832 also helps to reduce the equipment and manufacturing footprint which saves production space. It is cured via UV light which in turn enables a lower energy consumption.
Loctite PE 8086 AB - Enhance Thermal Efficiency
Loctite PE 8086 AB is a thermally conductive potting material specially 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.
Loctite PE 8086 AB maintains optimal operating temperatures to ensure peak performance and mitigates long term performance degradation due to high temperatures, while protecting components from environmental factors, contaminants, and mechanical stress.
As a solvent free product that produces no VOCs during the curing process, it enables more sustainable manufacturing. Loctite PE 8086 AB mitigates resource consumption as it uses less abrasive materials, thereby reducing equipment wear and facilitating lower maintenance requirements.
