    • The present invention provides a secondary aqueous coating composition for coating sized glass fibers of a glass fiber strand, including a first water soluble, emulsifiable or dispersible curable acrylic polymer and a second water soluble, emulsifiable or dispersible curable acrylic polymer different from the first acrylic polymer, the secondary aqueous coating composition being essentially free of a urethane-containing polymer. Other aspects of the present invention include a strand of sized glass fibers having thereon the aforementioned coating composition and an optical fiber cable assembly including an optical fiber and a reinforcement strand of the sized and secondarily coated glass fibers. In an alternative embodiment of the present invention, the sized glass fibers of the reinforcement strand of the optical fiber cable assembly have thereon the dried residue of a secondary aqueous coating composition which includes a water soluble, emulsifiable or dispersible curable acrylic polymer and a wax material, the secondary aqueous coating composition being essentially free of a urethane-containing polymer.
    • 本发明提供一种二次水性涂料组合物,其用于涂覆玻璃纤维股的尺寸玻璃纤维,包括第一水溶性,可乳化或可分散的可固化丙烯酸类聚合物和不同于第一丙烯酸类聚合物的第二水溶性,可乳化或可分散的可固化丙烯酸聚合物 ,二次水性涂料组合物基本上不含有聚氨酯的聚合物。 本发明的其它方面包括其上具有上述涂料组合物的尺寸大小的玻璃纤维束和包括尺寸和二次涂覆的玻璃纤维的光纤和增强线的光纤缆线组件。 在本发明的替代实施例中,光纤电缆组件的增强绞线的尺寸的玻璃纤维上具有第二水性涂料组合物的干燥残余物,其包含水溶性,可乳化或可分散的可固化丙烯酸聚合物和蜡材料 ,二次水性涂料组合物基本上不含有聚氨酯的聚合物。
