Abstract
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: PA1 of component(s) exhibiting at least one epoxy reactive functional group, PA1 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.
