A method for the production of particularly reactive and low viscosity to form allophanates by actinic light curable groups and their use for the production of particularly scratch-resistant coatings

摘要

The present invention relates to a process for the production of particularly reactive and low viscosity reaction products of polyisocyanates, the activated, under the action of actinic radiation which react, with polymerization, ethylenically unsaturated groups, as well as the use of these reaction products in coating compositions and particularly scratch-resistant coatings obtainable therefrom.
