Abstract
The present invention relates to a sizing composition for a glass yarn, consisting of a solution whose solvent content is less than 5% by weight, this solution comprising at least 60% by weight of polymerizable components, at least 60% by weight of these polymerizable components being components with a molecular mass of less than 750 and these polymerizable components comprising at least one mixture capable of polymerizing:of component(s) containing at least one reactive acrylic function and/or at least one reactive methacrylic function, andof component(s) containing at least one reactive primary amine function and/or at least one reactive secondary amine function,at least 20% of the polymerizable components containing at least two reactive functions chosen from acrylic, methacrylic, primary amine and secondary amine functions.
