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.

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.
Optical Encapsulants for LED

Whether the goal is to optimize LED efficiency, reliability or cost of ownership, DuPont&#;s portfolio of high-performance optical-quality silicone encapsulants offers a full range of solutions for LED modules.
Offering optimized refractive index (RI) values and a versatile selection of viscosities and hardnesses, our portfolio of optical encapsulants expands design freedoms ideal for a variety of middle and high-power LED package types, including surface-mount, lens mold and chip-on-board architectures. Duroptix® optical encapsulants also expand processing options, from dispensing materials to enabling overmolded lens designs.
Improve efficiency
As the global leader in optical-quality phenyl silicones, we bring a decade of rigorous research and technology development backed by a rich patent portfolio. Our cutting-edge phenyl encapsulant materials offer refractive indices as high as 1.54 to enable LED designs that deliver up to 7 percent greater light output compared to those based on methyl chemistry. Achieving a comparable improvement from an LED chip would require significant investment.
Protect and seal for greater reliability
Duroptix® optical encapsulants offer higher thermal stability compared to conventional organic LED encapsulation materials, enabling longer maintenance of light quality. In addition, our phenyl-based encapsulants offer a comparatively stronger gas barrier than methyl technology to minimize degradation of light output efficiency by protecting delicate silver-plated LED electrodes from sulfur attack. At the same time, our methyl-based materials offer slightly greater photothermal stability to minimize yellowing and performance degradation after long exposure to high heat and strong light.
