wherein the second primer consists of, in percentages by mass, 50-60% of polyurethane acrylate, 30-50% of 1,6-hexamethylene diacrylate, 2-4% of a photoinitiator, and 0.1-1.0% of silica; and
wherein the first coating consists of, in percentages by mass, 35-40% of polyurethane acrylate, 35-45% of tri (propylene glycol) diacrylate, 10-15% of ethoxylated trimethylolpropane triacrylate, 2-5% of a photoinitiator, and 5-10% of talc.
