| 20-3302 is a two component, ultra clear epoxy system. It provides excellent optical transmission along with outstanding adhesion and electrical properties. This high purity grade polymer system is formulated with proprietary ultraviolet protectors to minimize yellowing of the cured epoxy. This adhesivepotting compound, when UV aged in a QUV Weatherometer, outperforms other commercially available epoxy systems. 20-3302 is a low viscosity system designed for L.E.D. encapsulating, fiber optics, and any potting or adhesive application requiring optimum clarity. This epoxy system also provides a bubble free and glass smooth finish. 20-3302NCLV is a lower viscosity version of 20-3302. Both resins utilize the same curing agent. Features: Low viscosity Water clear Outstanding electrical properties Bubble free castings&& |
