Title (EN) A SOLVENT-FREE, RADIATION-CURABLE, OPTICAL GLASS FIBER COATING COMPOSITION AND SOLVENT-FREE METHOD FOR MAKING A SOLVENT-FREE, RADIATION-CURABLE, OPTICAL GLASS FIBER COATING COMPOSITION
(FR) COMPOSITION SANS SOLVANTS ET DURCISSABLE PAR RAYONNEMENT DESTINEE AU REVETEMENT DE FIBRES OPTIQUES EN VERRE, ET PROCEDE DE PRODUCTION D'UNE TELLE COMPOSITION SANS SOLVANTS
Abstract:
(EN) The invention relates to a solvent-free radiation-curable, optical glass fiber coating composition containing: a) a urethane oligomer having a functional group capable of polymerization in the presence of actinic radiation, with an average functionality of at least about 1.2, having a vinyl addition polymer as backbone; b) a urethane compound having a functional group capable of polymerization in the presence of actinic radiation, with an average functionality of at least about 1, containing an organic moiety having about 5 or more carbon atoms as backbone; c) a reactive diluent. Furthermore, the invention relates to a solvent-free method for producing a solvent-free, radiation curable urethane oligomer composition.
(FR) Cette invention concerne une composition sans solvants et durcissable par rayonnement qui est destinée au revêtement de fibres optiques en verre, et qui comprend les éléments suivants: (a) un oligomère d'uréthane possédant un groupe fonctionnel capable d'une polymérisation en présence d'un rayonnement actinique, ayant une fonctionnalité moyenne d'au moins environ 1,2, et possédant un polymère d'addition vinyllique à titre de squelette; (b) un composé d'uréthane possédant un groupe fonctionnel capable d'une polymérisation en présence d'un rayonnement actinique, ayant une fonctionnalité moyenne d'au moins environ 1, et contenant à titre de squelette, un fragment organique comportant environ 5 atomes de carbone ou plus; et (C) un réactif diluant. Cette invention concerne également un procédé ne faisant pas appel à des solvants et permettant de produire une composition à base d'oligomères d'uréthane durcissable par rayonnement et sans solvants.
