Use of Adhesives and Sealants for Hermetic Wire Feedthroughs
The hermetic sealing of electrical and optical feedthroughs is a critical area for assuring the longevity and reliability of devices such as optical assemblies, thermocouples, EV battery packs, power supplies, transformers, and generators. Epoxy adhesive sealing or potting offers exceptional processing flexibility, especially for hermetically sealing wire feedthroughs composed of many conductors through a small diameter housing. Epoxy polymer is inherently electrically insulative and exhibits high adhesion to materials including metals, ceramics, glass, and some plastics, providing a greater range of adhesion compared with glass and ceramic sealing. The epoxy fabrication and curing process allows for a wide array of different conductors to be hermetically sealed within a housing. Download this white paper to learn more about this process and the adhesive requirements for hermetic wire feedthroughs, EV battery pack applications, and a case study from NASA.
