Epotek MED-353ND is the medical-grade adaptation of the world-renowned “Gold Standard” 353ND, specifically tested and certified to meet USP Class VI and ISO 10993 biocompatibility standards. This high-performance, two-component epoxy is engineered for the most rigorous medical fiber optic applications, including surgical laser delivery systems, endoscope light guides, and surgical robotics. It features an exceptionally high glass transition temperature and superior thermal resistance, ensuring joint stability during repeated sterilization cycles. A critical quality-control feature is its built-in color-change indicator, which transitions from a clear-amber to a deep reddish-brown once fully heat-cured, providing technicians with an unmistakable visual confirmation of a successful bond. With elite-level transmission in the 800nm to 1600nm range and a moisture-proof seal that withstands autoclaving and chemical sterilization, MED-353ND is the definitive choice for manufacturers requiring a biocompatible adhesive that delivers absolute reliability under extreme thermal and mechanical stress.
