Epoxy Resin & Polyurethane Compounds for LED Encapsulation
Our epoxy and polyurethane resin formulations insulate fragile wire bonds from moisture, thermal shock, vibration, and other potentially damaging conditions. Liquid epoxy is poured into the LED chamber and bracketed to the desired shape. Our high-efficiency ovens then cure the mold. Epic Resins' epoxy manufacturing process exceeds all industry expectations for quality, cost, and dependability.
Custom Formulated LED Encapsulation Resins
Epic Resins' expert formulators excel in customizing formulations to fit the specific needs of our customers. If you see an Epic Resins compound that doesn't entirely fit your needs, we'll adjust the formula to work with your unique product properties. Our advanced development and testing labs allow us to create new formulas, so LED lighting manufacturers are certain to find the perfect epoxy or polyurethane compound for their products.
Epic Resins has decades of experience in specialty epoxy and polyurethane resins. Our professional staff uses superior customer service to work with clients to solidify their manufacturing production process. Our expertise provides clients the ability to maximize proactive product development and supply consistency to achieve maximum value, in both short production runs and ongoing industrial bulk supply needs.
