The common methods to improve the hardness and abrasion resistance for UV resins and coating are briefly described in this article.In order to overcome the defects that inorganic particle is dispersion heterogeneous and settleable in UV resins and coating,we introduces how to make one kind of UV cured nano-silica hybrid polyurethane acrylate and coatings!This polyurethane acrylate and its coating have characteristics of lower viscosity,lower content of nano-particles.The coating has high hardness and good abrasion resistance after fully curing by UV.It has extensive applications in the furniture industry such as wood floor,cabinet and other fields of abrasion resistnace coating fields.
