Abstract: There is provided a radiation-curable coating composition containing oligomers that each have two end groups X1 and X2, wherein the end groups X1 and X2, which may be the same or different, are a photoinitiator group or an adhesion promoter group. The coating composition may exclude the presence of non-reactive photoinitiator groups and non-reactive adhesion promoter groups, each of which would fail to covalently bond itself to an oligomer backbone.

Abstract: The present invention provides a method and apparatus for curing a coated fiber, comprising either two fiber coating curing stages separated by a cooling stage, or two fiber coating curing stages separated by a distinct time interval, or both. One of the two fiber coating curing stages responds to the coated fiber, and provides a partially cured fiber coating. The other of the two fiber coating curing stages responds to the partially cured coated fiber for further curing the coating of the fiber. In one embodiment of the invention, a cooling stage is placed between the two curing stages, while in the other the curing stages are placed a set distance apart such that polymerization of the coating initiated by the first curing stage has time to complete prior to the coating being irradiated by the second curing stage. The cooling stage is used to actively remove heat generated during the cure process from the fiber coating, while the time delay is used to allow complete polymerization to occur before subsequent irradiations. These embodiments of the present invention can be used separately or in combination to achieve optimal fiber coating cure.

Abstract translation: 本发明提供了一种用于固化涂覆纤维的方法和装置，其包括由冷却阶段分离的两个纤维涂层固化阶段，或两个以不同时间间隔分开的两个纤维涂层固化阶段，或两者。 两个纤维涂层固化阶段之一响应于涂覆的纤维，并提供部分固化的纤维涂层。 两个纤维涂层固化阶段中的另一个响应于部分固化的涂覆纤维，以进一步固化纤维的涂层。 在本发明的一个实施方案中，将冷却阶段放置在两个固化阶段之间，而在另一个固化阶段中，固化阶段间隔一定距离放置，使得由第一固化阶段开始的涂层的聚合在第 涂层被第二固化阶段照射。 冷却阶段用于主动地从纤维涂层去除固化过程中产生的热量，而使用时间延迟以允许完全聚合在随后的照射之前发生。 本发明的这些实施方案可以单独使用或组合使用以实现最佳纤维涂层固化。
