Radiation-curable coatings suitable for high-speed application onto optical fibers

Abstract:

Inner and outer primary and matrix material compositions which, after curing, exhibit a high degree of uniformity after curing even when the coating is applied onto optical fibers at relatively high shear rates, e.g., such as those experienced at high optical fiber coating line speeds. These compositions are provided in significant part by the selective incorporation of at least one radiation-curable oligomer into the compositions. In particular, and with respect to inner primary coatings, the oligomer should be selected so that the value m of an uncured radiation-curable inner primary coating composition in the equation τ = K ⁢ ⁢ λ ⁢ ⁢ γ 1 + ( λ ⁢ ⁢ γ ) m ( I ) is advantageously equal to or greater than about 0.90.

Abstract(Chinese):

固化后的固化后的内外原料和基体材料组合物即使在以较高的剪切速率将涂料施加到光纤上（例如在高光纤涂布线速度下经历的那些）下也能在固化后表现出高度的均匀性。这些组合物在很大程度上通过将至少一种可辐射固化的低聚物选择性掺入组合物来提供。特别地，对于内部主要涂层，应该选择低聚物，使得在等式 $\begin{matrix} tau=KlambdaMI/ MROW>（I）有利的是等于或大于约0.90的/ MTABLE>。Information query Global Dossier EspacenetIPC分类: C 化学；冶金 C09 染料；涂料；抛光剂；天然树脂；黏合剂；其他类目不包含的组合物；其他类目不包含的材料的应用 C09K 不包含在其他类目中的各种应用材料；不包含在其他类目中的材料的各种应用 C09K3/00 不包含在其他类目中的材料Find Agent Technical Fields Latest Chinese Patents Latest US Patents Semantic Search newFriend Links 专利交易门类知识网企业财务服务中科微点API Changelog WeChat Group © 2025 Shanghai Xiaoyi Network Technology Co., Ltd. .
