Abstract
An aqueous coating composition for fibers comprising, a thermoplastic polyurethane latex, and acrylic latex, the balance being water. The coating also contains a paraffin wax or a second acrylic latex. When coated onto a bundle or strand of glass fibers the coated glass fibers are useful in optical fibers and cables. This coating is especially useful in reducing water wicking into the coated glass strand.
