Liquid, UV-curable coating material for wood, especially wooden parts inside cars, contains a mixture of mono-, oligo- and poly-meric polyfunctional (meth)acrylate compounds and a reactive diluent

摘要

A liquid, UV-curable coating material (I) comprises: (a) 5-80 wt.% of a mixture of monomeric, oligomeric and polymeric polyfunctional acrylates and/or methacrylates; (b) 5-75 wt.% of a reactive diluent; (c) 0.1-5 wt.% thixotropic agent; (d) 0.1-10 wt.% photoinitiator; and (e) 0.05-20 wt.% additives A liquid, UV-curable coating material (I) comprises: (a) 5-80 wt.% of a mixture of monomeric, oligomeric and polymeric polyfunctional acrylates and/or methacrylates; (b) 5-75 wt.% of a reactive diluent; (c) 0.1-5 wt.% thixotropic agent; (d) 0.1-10 wt.% photoinitiator; and (e) 0.05-20 wt.% additives An Independent claim is also included for a method for the production of a coating on a prepared wooden surface by applying several layers of (I) with a film thickness of 50-500 microns by hot spraying at 35-80 deg C and gelling each layer, after application, by UV irradiation.
