Abstract:
1. A coating material comprising components: a. 40 to 90 wt. % of at least one oligomeric substance selected from the group consisting of epoxy (meth)acrylates, polyester (meth)acrylates, polyether (meth)acrylates, and polyurethane (meth)acrylates, wherein said oligomeric substance is linear or branched and contains at least two unsaturated double bonds; b. 5 to 60 wt. % of at least one low molecular weight (meth)acrylate selected from the group consisting of monofunctional, difunctional, trifunctional and polyfunctional (meth)acrylate compounds; c. 0.1 to 20 wt. % of at least one (meth)acrylate compound different from a and b containing one or more acidic groups; and d. 0.1 to 20 wt. % of at least one auxiliary substance selected from the group consisting of adhesion promoters different from c, flow-control agents, defoaming agents, light stabilizers, dyes, pigments, biocides, fillers and photoinitiators; wherein 2.0 to 9.7 wt. %, based upon total coating material, of the at least one low molecular weight (meth)acrylate is selected from difunctional, trifunctional and polyfunctional (meth)acrylate compounds; and wherein at least one of nanoparticulate aluminum oxide or hydrophobic silica is present in highly dispersed form in the coating material and said components are selected such that the coating material has a viscosity of less than 1000 mPas within a temperature range of 0 to 90° C.
