Epotek MED-301-2FL is a medical-grade, two-component, optically clear epoxy specifically designed for applications requiring high flexibility and biocompatibility. This material is tested to ISO 10993 standards for medical safety and is engineered to provide a low-stress bond that can absorb mechanical vibration and withstand extreme thermal cycling. Its flexible nature makes it the definitive choice for potting fiber optic light guides and bonding components in catheters, endoscopes, and wearable medical sensors that must move or flex during use. MED-301-2FL maintains excellent transmission in the visible and IR regions while offering a robust environmental seal against moisture and biological fluids. With its low viscosity and room-temperature curing capability, it ensures easy processing for delicate assemblies where high-heat stress must be avoided. It provides superior adhesion to medical technical plastics and metals, delivering a durable, compliant bond that ensures patient safety and device longevity.
