Resin coating on optical fibers

Resin coating on optical fibers. (Hitachi Chemical Co., Ltd.In this study， 60676-86-0 and 108-32-7 are also used., Japan). Jpn. Kokai Tokkyo Koho JP 58204847 A2 29 Nov 1983 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C03C025-02; C03B037-12; G02B005-14. APPLICATION: JP 82-88425 25 May 1982. DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Optical fibers are coated with a mixt. contg. epoxy resin and a catalyst and hardened by radiation energy. Thus, a 150m diam. SiO2 glass-based optical fiber was passed through a mixt. contg. bisphenol A diglycidyl ether polymer [25085-99-8] 60, phenyl glycidyl ether [122-60-1] 40, and a propylene carbonate [108-32-7] soln. contg. triphenylsulfoniumhexafluoroantimonate 5 parts at 0.5 m/s and irradiated with UV. The resin-coated optical fiber had tensile breaking load 1.52 kg, compared to 0.53 without the resin coating. .
