Title
(EN) FIBER COATING COMPOSITIONS WITH ACYLGERMANE PHOTOINITIATORS
(FR) COMPOSITIONS DE REVÊTEMENT DE FIBRES COMPORTANT DES PHOTO-INITIATEURS À BASE D'ACYLGERMANE
Abstract
(EN)
The present disclosure provides coating compositions that can be cured at fast rates as well as coatings and cured products formed from the coating compositions. The coating compositions include an acylgermane photoinitiator that leads to fast cure speeds. The coating compositions include primary coating compositions and secondary coating compositions. The coating compositions can be cured to form primary and secondary coatings of optical fibers. The primary coatings feature low Young's modulus and high tear strength. The primary coatings provide good microbending performance and are resistant to defect formation during the fiber draw process and subsequent handling operations. The secondary coatings feature high Young's modulus and good puncture resistance.

La présente invention concerne des compositions de revêtement qui peuvent être durcies à des vitesses rapides ainsi que des revêtements et des produits durcis formés à partir des compositions de revêtement. Les compositions de revêtement comprennent un photo-initiateur à base d'acylgermane qui conduit à des vitesses de durcissement rapides. Les compositions de revêtement comprennent des compositions de revêtements primaires et des compositions de revêtements secondaires. Les compositions de revêtement peuvent être durcies pour former des revêtements primaires et secondaires de fibres optiques. Les revêtements primaires présentent un faible module de Young et une résistance à la déchirure élevée. Les revêtements primaires assurent de bonnes performances de microcourbure et résistent à la formation de défauts durant un processus d'étirage de fibres et les opérations de manipulation qui suivent. Les revêtements secondaires présentent un module de Young élevé et une bonne résistance à la perforation.
