EPO-TEK¬Æ 301-1 is a two-component, room temperature curing epoxy known for its low viscosity and excellent optical and mechanical properties. It is designed for applications requiring high spectral transparency, with over 97% transmission from 400 to 1400 nm and 92% from 1400 to 1600 nm. The product has a mix ratio of 20:5 by weight and a pot life of 1 to 2 hours at 23¬8C, with a recommended cure temperature of 65¬8C for 2 hours. The epoxy exhibits a glass transition temperature of ,â 65¬8C and a degradation temperature of 390¬8C. It has a Shore D hardness of 80 and demonstrates strong adhesion to various substrates, including glass, metals, and engineering plastics. EPO-TEK¬Æ 301-1 is suitable for semiconductor applications, optical encapsulation, PCB potting, and fiber optic sealing, making it versatile for demanding optical and electronic applications. The product has a shelf life of one year at room temperature and should be stored properly to maintain its properties.
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®
