CASE STUDY UV15X-6Med-2: Used as a Biocompatible Encapsulant for a Wireless, Nerve Stimulation System Overview of UV15X-6Med-2 UV15X-6Med-2 is a one-component, medium-viscosity UV-curable system that offers high flexibility, toughness, abrasion resistance, and strong adhesion to substrates including glass, polycarbonates, acrylics, plastics, metals, and rubbers. It cures within 10-30 seconds under 320-365 nm UV light and provides excellent toughness, optical clarity, and electrical insulation. Its biocompatibility (passes USP Class VI and ISO 10993-5 cytotoxicity testing) and water resistance...

UV15X-6Med-2 generally cures in 10-30 seconds at ambient temperatures when exposed to 320-365 nm UV light, and can cure in sections approaching 1/4 inch thick without oxygen inhibition. Results The protective function of UV15X-6Med-2 was evaluated by prolonged immersion in phosphate-buffered saline (PBS) to simulate physiological conditions. The salt content of PBS is challenging for electronics because it accelerates corrosion and mimics the ionic conductivity of bodily fluids. Despite continuous exposure to PBS for 20 days, the device maintained consistent stimulation (Figure 2) throughout...
