Epoxy Technology EPO-TEK® OM125 Optical Epoxy
Categories:	Polymer; Thermoset; Epoxy
Material Notes:	Product Description: EPO-TEK® OM125 is two component, high Tg, optical epoxy designed for bonding multi-mode fiber optic connectors. Advantages & Application Notes: Color coded blue for easy operator ID on the manufacturing floor. A reliability test report is available when using MM fibers and MT ferrule connectors. It is compatible with Telcordia GR1221 and GR326. Versatility in curing from 23°C to 80°C. When used in optical beam pathway, a non-blue version is available. A low viscosity allows for wicking and capillary process methods. Can also be used for potting and encapsulation. Information Provided by Epoxy Technology
