A string binder (12) is disclosed which is useful for making reinforcing articles for use in the manufacture of molded composite articles. The string binder comprises a fibrous carrier substrate (1) covered with a solidified coating (5) comprising a binder resin material having an acid value of less than about 30 mg KOH/g of resin. Additionally, the fibrous carrier substrate may be coated with at least one layer (4) of a pre-coating or post-coating comprising a catalyst composition. The string binder may be co-roved with one or more ends of a separate fibrous reinforcing material to make a product suitable for use in various molding applications.
