ABSTRACT:
The present invention provides an optical fiber cable assembly including an optical fiber and a reinforcement strand including a plurality of sized glass fibers positioned about the optical fiber, the strand having thereon a dried residue of a secondary aqueous coating composition which is essentially free of a urethane-containing material and includes a first polymer prepared by vinyl addition polymerization of a first monomer component including a first vinyl aromatic monomer and an acrylic monomer and a second polymer different from the first polymer, the second polymer being prepared by vinyl addition polymerization of a second monomer component including a curable polymer of a second vinyl aromatic monomer, wherein the surface of the strand wicks water at a rate of less than about 25.4 millimeters (one inch) in about six hours at a temperature of about 25.degree. C. A method of reducing the wicking of water along the surface of a glass fiber strand is also provided.
