The IOC-172 optical material from Inkron, a NAGASE Group company, offers a high refractive index optical coating with good transmittance to provide increased end product performance. IOC optical materials are UV-curable, organo-siloxane resins with multi-functional crosslinking reactivity, which provide high refractive index and transmittance. Retention of transparency over time and high thermal stability makes them excellent candidates to consider for high reliability applications. IOC-products exhibit low shrinkage during cure and essentially no out-gassing after cure. Viscosity can be adjusted to allow easy use in a variety of machine configurations.
