Elaplus case sharing and product recommendation of sealing reinforcement for the tail wire harness of lamp head

In the modern automotive manufacturing and LED lighting industries, the sealing and reinforcement of the wiring harness at the rear of the lamp head has always been a key concern for technicians. High quality adhesive sealing materials not only determine the appearance and aesthetics of lamp head products, but also directly affect the long-term stability and safety of the products. This article will start from practical cases and analyze in detail the technical requirements, application process, testing standards, and our recommended high-performance sealant – Elaplus SIPC 2150 white sealant – for sealing and reinforcing the wire harness at the tail of the lamp head. It will help engineers and technicians better grasp the key points of construction and achieve high-quality sealing and reinforcement effects. 1、 Project background and sealing requirementsIn the tail area of the lamp head, due to the dense arrangement of electrical wiring harnesses and long-term exposure to complex environments such as temperature, humidity, and oil pollution, sealing and reinforcement work is particularly critical. In traditional craftsmanship, improper sealing often leads to the intrusion of water vapor and dust, and even causes problems such as circuit short circuits, accelerated aging, and decreased performance of lighting fixtures. Therefore, the sealant selected for this case must meet the following strict requirements:Adhesive force requirement: The final test tensile force must be greater than 30N to ensure that the sealing layer will not peel off due to external forces during actual use.Aging resistance test: After passing the double 85 test for 5000H, the product ensures long-term stable operation in high temperature environments.Color requirement: The product should appear transparent or white to meet the appearance requirements and coordinate with the car lights and interior style.These technical requirements ensure the excellent performance of the sealant in various extreme environments, thereby effectively improving the durability…
