Abstract:
The present invention relates to a coating composition that provides improved scratch and stain resistance. The coating composition includes a curable film-forming resin having at least two multi-functional (meth)acrylates and a plurality of particles dispersed within the resin, said particles comprising (i) inorganic nanoparticles and (ii) wear resistant mineral particles. The wear resistant mineral particles have an average particle size of greater than 3.5 microns.
