Abstract
Radiation-curable compositions, having high elongation at break and toughness after cure can include the following pre-mixture components: PA0 a) a polymer, oligomer or monomer having at least one (meth)acrylate functional group; PA0 b) an oligomer or monomer, exclusive of (meth)acrylate functional groups, having an ethylenically unsaturated functional group; and PA0 c) an elongation promoter; wherein the composition, after radiation-cure, has an elongation at break of at least about 200%. Glass substrates and optical fibers are coated with the radiation-curable composition. Monofilament fiber or a plurality of fiber filaments, such as sewing thread, are coated with the radiation-curable binder composition, which after cure, demonstrates high elongation at break.
