Practical case of reinforcing automotive electronic connectors | A glue solves the problem of dispensing and improves sealing reliability!
With the rapid advancement of intelligence and networking, the complexity and density of automotive electronic systems continue to increase, and electronic connectors, as the core connecting components, are facing higher requirements for sealing, reliability, and durability. Today we will share a practical case where we successfully solved the problems of fluidity and adhesive operation in joint reinforcement by selecting the appropriate sealant. Customer Background: Challenges for Automotive Electronics ManufacturersThe client is a Tier 1 supplier of automotive electronics, with a long-term focus on the research and manufacturing of high-end intelligent control systems. Its electronic connector is located in the engine control unit wiring harness area and is exposed to complex environments such as alternating cold and hot, moisture, and vibration for a long time. The original adhesive solution exposed two problems in actual mass production:The viscosity of the glue is too high, making it difficult to accurately apply it to a 3mm wide slot;The curing speed is slow, the efficiency is low, and it affects the production line rhythm.The customer explicitly requested a low viscosity, self leveling, easy to operate, and reliable sealing solution for the sealant.List of adhesive requirementsRequirements for adhesive application scenariosThe reinforcing glue at the end of the joint needs to have good fluidity and permeabilityGlue with a width of 3mm needs to have self leveling characteristics, and there should be no residue during fine operationEasy to operate, suitable for manual or automated dispensing systemsLong term reliability to resist moisture, dust, and electrical interference, ensuring electronic stabilityRecommended solution: RTV SIPC 9030 self leveling sealantIn response to the above pain points, we recommend using RTV SIPC 9030 silicone sealant for our customers. This is a neutral dealcoholized, single component RTV silicone sealant developed specifically for PIN needle sealing, connector protection, and other scenarios, especially suitable for sealing and…
