Abstract
The present invention provides aqueous coating compositions adapted to coat a fiber strand having thereon a sizing composition. The aqueous coating compositions include a urethane-containing polymer and a polymer prepared by addition polymerization of a monomer selected from the group consisting of acrylic acid, methacrylic acid and a mixture thereof. Also provided by the present invention are sized fiber strands coated with the secondary coating composition and composites reinforced with the same.
