EPO-TEK¬Æ 377 is a two-component, high-temperature epoxy designed for semiconductor and optical applications. It has a recommended cure temperature of 150¬8C for one hour and features a mix ratio by weight of 1:1. The specific gravities of the components are 1.15 for Part A and 1.22 for Part B. This epoxy exhibits a pot life of 24 hours and a shelf life of one year at room temperature, or six months at -40¬8C. The product is characterized by a glass transition temperature of at least 95¬8C and a low viscosity, making it suitable for various application methods including pouring, brushing, and automated dispensing. EPO-TEK¬Æ 377 is noted for its optical properties, with a spectral transmission of over 90% in the 600-1000 nm range and 98% from 1000-6800 nm. It is also resistant to a variety of chemicals, including salt water and certain acids. This epoxy is particularly recommended for applications such as MEMS fabrication, wafer-to-wafer bonding, and hermetic sealing in opto-electronic packaging. It is NASA-approved for low outgassing, making it suitable for demanding environments.
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®
