Abstract

Optical glass fibres are primary coated on line during fibre drawing with a low-modulus buffer coating. Before cabling, a thermoplastic secondary coating is applied by extrusion. This paper deals with the primary buffer coating. The main requirements of the primary coating materials are related to processing speed, optical functioning and fibre strength. On-line coating during fibre drawing is essential for the protection of the brittle fibre surface. UV-curable polyetherurethane acrylates and poly(dimethyl-co-methylphenyl)siloxane acrylates have been investigated for the primary buffer coating of optical fibres. Curing behaviour, E-modulus, glass transition temperature and refractive index have been studied in relation to the molecular structure of both acrylate types.
