GLASS THREAD COATED WITH A PREPARATION COMPOSITION, THE PREPARATION COMPOSITION FOR THE GLASS THREADS, METHOD OF USING SUCH COMPOSITION AND PRODUCTS RESULTING THEREFROM

摘要

The present invention relates to a sizing composition for glass strands composed of a solution with a viscosity of less than or equal to 400 cP comprising less than 5% by weight of solvent and comprising at least one thermally polymerizable base system, the said base system comprising at least 60% by weight of components with a molecular mass of less than 750 and comprising at least 60 % by weight of a mixture:of component(s) exhibiting at least one epoxy reactive functional group,and of component(s) exhibiting at least one anhydride reactive functional group.The invention also relates to a process using this composition and to the strands obtained according to this process and coated with the said composition.
