  • UV-CURABLE COATING COMPOSITION
    Publication number: 20160017169
    Abstract: The present invention relates to a coating composition comprising: a) one or more aliphatic polymer precursors selected from components A.1 and optionally A.2: A.1) aliphatic oligomers containing urethane or ester bonds and having at least two acrylate functions per molecule, or mixtures of said oligomers, and A.2) aliphatic reactive diluents having at least two acrylate groups per molecule, or mixtures of said reactive diluents, b) optionally one or more finely divided inorganic compounds, c) an organic UV absorber, d) optionally a free radical scavenger from the HALS class, e) optionally one or more levelling additives, f) optionally one or more solvents, and g) a photoinitiator. It further relates to a process for the coating of a substrate, to the coated substrates obtainable in this way, and to the use of the coated substrates.
