Summary: | The present invention relates to an aqueous UV curable dispersion comprising at least the reaction product formed from: a) at least one polyisocyanate having an average isocyanate functionality of at least 2.2; wherein preferably at least one polyisocyanate is an oligomeric polyisocyanate having structural units of urethane, biuret, allophanate, iminooxadiazindione and/or isocyanurate, b) at least one acryloyl group-containing monohydroxy functional compound, c) at least one component containing a non-ionic hydrophilizing group and having at least one further isocyanate-reactive group, and d) at least one diol, triol, diamine and/or triamine wherein the reaction product does not have an ion source group or an ionic hydrophilizing group; a preparation method thereof; the use of the dispersion for producing a glass fiber sizing agent; a glass fiber sizing agent comprising at least such a dispersion; glass fibers equipped with a sizing agent obtainable using such a dispersion; a method for manufacturing a glass |
