Abstract

The invention relates to new, low viscosity radiation-hardenable urethane acrylates prepared from oxalkylated polyols with 25 to 75 mole % of a polyol having a degree of oxalkylation between 3 and 5 and 75 to 25 mole % of a polyol having a degree of oxalkylation between 8 and 25, the resulting coatings having improved abrasion resistance, as well as their use as coating compositions, in particular for flooring materials.
