EPO-TEK® 301-2G is a two-component optically transparent epoxy designed for various applications in the optical market. It features a recommended cure condition of 80°C for 3 hours and has a mix ratio by weight of 100:35. The product exhibits a specific gravity of 1.16 for Part A and 0.95 for Part B, with a pot life of 8 hours at room temperature. The shelf life is one year for bulk and six months for syringe packaging when stored appropriately.
This epoxy demonstrates excellent optical properties, with a spectral transmission of = 98% across the 440-1440 nm range and a refractive index of 1.5323 at 589 nm. It is resistant to yellowing under continuous UV light exposure for up to 17 days, making it suitable for applications such as LCD optical lamination and LED encapsulation. The adhesive provides strong bonding to various substrates, including glass, quartz, metals, wood, and most plastics.
EPO-TEK® 301-2G is also suitable for semiconductor applications, including underfill for flip chips and glob top encapsulation. Its low-stress characteristics make it ideal for bonding optics in OEM and scientific instruments. The product is compliant with impact and vibration resistance requirements, and it can be used for fiber optic applications, including bundling fibers and mounting optics.
We have served the optical market since 301 was introduced in 1969. Our products encapsulate, coat, bond and seal plastics, crystals and glass together for optical components, such as prism, filters, and mirrors. EPO-TEK® fabricated components are the building blocks of camera, laser, telescope, spectrometer and fiber-optic circuitry. Additionally, they ruggedize and toughen LCD touch panels as the transparent adhesive for plastic lamination. Through liquid injection molding, our optical epoxies form the plastic cap over LEDs. More recently, solar cells require our UV curing resin for harvesting sunlight, while providing watertight protection. EPO-TEK®
