Material Notes:
Product Description: EPO-TEK® 320 is a two component, black-colored and optically opaque epoxy designed for optical, medical, and optoelectronic packaging of semiconductor devices and components. It is a widely used fiber-optic grade epoxy.Advantages & Application Notes: Optically opaque between IR and VISIBLE regions of light, including 185 – 2500 nm rangeIt can be used for room temperature curing, low temp, or box oven elevated temperature cure.Many modifications are available, such as viscosity, electrical insulation, Tg, and flexibility. Suggested applicationsOptical:blocking light in photonics packaging through VIS and NIR range; sensor packaging including IR detectors packaged in TO-cansbonding of various optics including lens, prism, diodesadhesion to metals, most plastics, and glasses.Fiber Optic: sealing / potting fibers into the boot, ferrule, or fiber feed-through of the package wallMedical: bonding/ potting/ sealing of optics used for imaging related electronics; complies with USP Class VI biocompatibility standards The low viscosity nature allows syringe dispensing and automation, hand, brushing, roller coating, tooth-pick or spatula, and pour or dipping.Information Provided by Epoxy Technology
