Product Description
EP21LVMed is a two-component, low-viscosity medical-grade epoxy formulated for high-performance bonding, sealing, coating, casting, encapsulating and potting in medical device and healthcare applications. It cures at room temperature or faster at elevated temperatures. Recommended cure schedule for optimized properties and biocompatibility: overnight at room temperature followed by 2–3 hours at 150–200°F. The system mixes 1:1 by weight and contains no solvents or diluents. Color: Part A clear, Part B amber.
