  • AQUEOUS SIZING FOR PRODUCING GLASS FIBRE PRODUCTS
    Publication number: 20100273375
    Abstract: An aqueous sizing is provided for treating glass fibers, in particular for producing roving fibers, glass staple fibers and cut reinforcing fibers in a thermally and chemically resistant glass, and also to glass fibers coated with the sizing. The sizing protects the glass fibers against scuffing and thus from mechanical damage.
