<p>Radiation curable coating compositions that contain an acrylate-capped polyether urethane, a low molecular weight polyfunctional acrylate, a monofunctional acrylate and, optionally, a photo-initiator are described. When cured, the coating compositions are sufficiently hard and flexible to serve as an overprint coating on sheet metal which is to undergo metal forming operations.</p> |
