Beschreibung
Zusammenfassung:	A string binder 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 covered with a solidified coating 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 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.
