The high-tolerant UV environment-friendly clear
varnish for Americian
solid wooden cabinet comprises base coat and finishing coat, which are used cooperatively; the base coat is prepared from the following materials by
mass percent: 10 to 15 percent of modified
acrylate, 30 to 35 percent of modified
urethane acrylate, 30 to 40 percent of active
monomer, 5 to 6 percent of
photoinitiator, 10 to 15 percent of filler; the finishing coat is prepared from the following materials by
mass percent: 15 to 20 percent of modified
polyester acrylate, 25 to 35 percent of modified
epoxy acrylate, 35 to 45 percent of active
monomer, 4 to 6 percent of
photoinitiator, 5 to 10 percent of
extinction powder. Performing the full-process automated painting construction by virtue of spraying equipment, the
