Epo-Tek® ET383ND Heat Cure Epoxy (2.5G)

EPO-TEK® 383ND is a two-component, high-temperature, electrically and thermally insulating epoxy. It is designed as a longer pot life version of EPO-TEK 353ND. This 100% heat-cured epoxy is formulated for bonding glass, ceramic, and metals. 2.5-gram packet.

Features:

• Long 8-hour pot life allows for use over an entire shift.
• Capable of high performance in fiber optic applications; designed to meet Telecordia 1221.
• Low viscosity allows for wicking and capillary dispensing.
• Strong transmission in the near IR; optimal for sealing fiber to ferrules, transmitting light in the optical pathways from 800-1,500 nm.
