The invention relates to the electronic application-
coating field, in particular to uv-curing
coating with high wearing resistance and
vacuum coating. The compositions and contents of the invention are: 10 wt percent to 30 wt percent of difunctional group
polyurethane acrylate, 10 wt percent to 40 wt percent of high functional group
polyurethane acrylate, 5 wt percent to 20 wt percent of high functional group
acrylate monomer, 0 wt percent to 15 wt percent of monofunctional group acrylate
monomer, 1 wt percent to 10 wt percent of acid
adhesive promoter, 1 wt percent to 6 wt percent of
photoinitiator, 0 wt percent to 5 wt percent of nano wearing resistance materials, 0.1 wt percent to 2 wt percent of additive and 10 wt percent to 50 wt percent of
solvent. The invention is designed for providing surface protection for
vacuum coating parts of electric products such as
mobile phone, MP3, and
digital camera, etc., and is characterized by good surface effect, good performances of ultrawear-resistance, high temperature and
humidity resistance, anti-cold thermal
cycling and anti-yellowing, etc., wherein, RCA wear can be up to more than 1500 times, which can effectively improve the service life of electric products. The invention effectively enhances the adhesion and wearing resistant performance of the uv-curing and
vacuum coating dope, solves the matching problem of the bottom and surface
lacquer of the uv-curing and vacuum
coating dope, and has broad university.
