Industrial electronic control unit thermal potting solution: PUR 1680 high-performance potting adhesive application case sharing
In modern industrial control systems, electronic control units (ECUs) are important components that ensure precise operation and safety of equipment. Especially in application scenarios that require high reliability, such as automobiles, robots, energy management, etc., ECU needs to operate continuously and stably under extreme environmental conditions. This not only places high demands on its functionality, but also poses severe challenges to its heat resistance, vibration resistance, and waterproofing. Therefore, choosing appropriate sealing materials can not only improve the reliability of ECU, but also effectively extend its service life. Background and ChallengesElectronic control units (ECUs) are typically installed in mechanical equipment or vehicles and are exposed to environmental conditions such as high temperatures, vibrations, moisture, and chemical corrosion for extended periods of time. For applications with high power current density, if the heat generated by the ECU cannot be effectively dissipated, it may cause component overheating, thereby affecting the performance of electronic components and even leading to malfunctions. Thermal management and mechanical protection have become important issues in design and application.Therefore, heat dissipation and management, especially thermal conductivity, have become key considerations when choosing sealing materials. In addition, the anti vibration and waterproof/dustproof properties must also meet industry standards to ensure the long-term stable operation of electronic control units in complex environments.Recommended product: PUR 1680 thermal conductive sealantPUR 1680 thermal conductive sealant is an ideal solution for addressing these challenges in industrial electronic control units. PUR 1680 A/B is a two-component solvent-free room temperature or heat cured resin elastomer composite used for two-component sealing and filling. The raw materials do not contain heavy metals, are environmentally friendly, have wide process operability, high physical properties of the finished product, and good adhesion to the substrate. It can be cured at room temperature or by heating, and can be deeply cured. The two-component…
