Glass yarn is coated with size comprising given amount of solvent and polymerizable components including reactive (meth)acrylate and primary and/or secondary amine of given molecular weight

摘要

Glass yarn is coated with a size composition comprising a solution of below 5 wt.% solvent and at least 45 wt.% polymerizable components, at least 40% being of molecular weight 750-5000, comprising a compound(s) with a reactive (meth)acrylic group(s) and a compound(s) with a primary and/or secondary amine reactive group(s). Glass yarn is coated with a size composition comprising a solution of below 5 wt.% solvent and at least 45 wt.% polymerizable components, at least 40% being of molecular weight 750-5000, comprising a compound(s) with a reactive (meth)acrylic group(s) and a compound(s) with a primary and/or secondary amine reactive group(s). Independent claims are included for; (1) A sizing composition for the yarns comprising a solution of below 5 wt.% solvent and at least 45 wt.% polymerizable components, at least 40% being of molecular weight 750-5000, comprising a compound(s) with a reactive (meth)acrylic group(s) and a compound(s) with a primary and/or secondary amine reactive group(s); (2) A composite comprising an organic and/or inorganic material(s) and the glass fibers; and (3) Production of sized glass fibers by drawing fibers, and coating with the size composition.
