Materials in the INKRON ILE-500 product family are formulated encapsulation resins designed for demanding LED applications. INKRON’s ILE-501A/B product includes heat curable, organosiloxane resins with multi-functional crosslinking reactivity. They provide films with a high refractive index (1.65@450nm) and transmittance as well as excellent thermal stability for effective extraction of light out of a wide variety of LED packages. High stability (e.g. maintaining high transparency over extended periods at elevated temperatures) makes them excellent candidates to consider for high reliability applications. ILE-501A/B products exhibit essentially no out-gassing after cure. Adhesion is excellent to metals, to most engineered plastics, and to glass and ceramics. Viscosity can be adjusted to allow easy dispensability in a variety of machine configurations.
