Application of adhesive sealant: case study on lead sealing of electric vehicle control box

With the booming development of the electric vehicle (EV) industry, more and more electronic control units (ECUs) and electrical components are facing increasingly harsh working environments. These control boxes usually need to maintain a high degree of protection, especially the sealing of the lead parts, to prevent moisture, dust, or chemical substances from penetrating and to avoid damage to the electrical system. Therefore, selecting appropriate adhesive materials has become one of the key factors that electric vehicle manufacturers must consider when designing electrical control systems.Customer Case Study Sharing——Application: Lead sealing of electric vehicle control boxLead sealing of electric vehicle control box ——Glue Point: Sealing of Outward Line——Functional requirements: For wire harness wrapping and bonding, with good filling properties between small and parallel wire harnesses——Viscosity range: 30000-70000 cpsBased on the above requirements, Yilian SIPC 1823 high-performance silicone sealant has become an ideal solution for sealing the leads of electric vehicle control boxes due to its excellent adhesion, good filling properties, and suitable viscosity.RTV SIPC 1823 neutral dealcoholized silicone adhesive sealant is a flowable moisture absorbing cured silicone gel that forms a flexible rubber body after curing, fully complying with the EU ROHS directive requirements. During the curing process, alcohol substances are released, which are non corrosive to materials such as polycarbonate (PC) and copper. They have good adhesive and sealing properties for the vast majority of materials, protecting electronic products in a stable state under harsh conditions. The lead sealing RTV 1823 silicone adhesive sealant of the electric vehicle control box has the following characteristics after curing:✔ Single component, easy to use, short non stick time✔ Excellent chemical resistance✔ Resist moisture, dirt, and other atmospheric components✔ Reduce mechanical stress and tension caused by mechanical, thermal shock, and vibration✔ Excellent electrical insulation performance, anti corona✔ Excellent outdoor aging resistance, with a service…
