Abstract
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.
