Abstract

A surface covering is provided. The surface covering includes a laminated panel and an ultra-violet (UV) curable surface coating applied to the laminated panel. The ultra-violet (UV) curable surface coating includes a first coating, a second coating, abrasive resistant particles, and an antimicrobial additive. The second coating is a composition distinctive of the first coating, the first coating is cured at a lower energy than the second coating, the second coating is cured at a higher energy to cure both the first coating and the second coating. The abrasive resistant particles include silicon carbide (SiC) particles wherein at least 50% of the silicon carbide (SiC) particles have a particle size of less than 45 μu. The antimicrobial additive selected from a group consisting of N-butyl-1,2-benzisothiazolin-3-one, alkyl dimethyl ammonium saccharinates, Zinc 2-pyridinethiol-1-oxide,10,10′-Oxybisphenoxarsine (OBPA), 4,5-Dichloro-2-octyl-4isothiazolin-3-one (DCOIT) and mixtures thereof.
