Abstract
The present invention relates to a sizing composition for glass threads which comprises a solution of a viscosity of less than or equal to 400 cP containing less than 5% by weight of solvent and containing at least one base system which can be polymerised under the action of ultraviolet radiation or an electron beam, the said base system comprising at least one component that has a molecular mass of less than 750 and that has at least one reactive epoxy group and comprising at least 60% by weight of one or more components that have a molecular mass of less than 750 and that have at least one reactive group selected from the following groups: epoxy, hydroxy, vinyl ether, acrylic and methacrylic. The invention relates also to a process using this composition and to the threads coated with the said composition.
