Solid polymeric highly durable surfacing
A solid surface comprises (i) a crosslinked acrylic or unsaturated polyester resin present in an amount no greater than 51 or 52 volume fraction percent, and (ii) no greater than 48 or 49 volume fraction percent of inorganic filler particles that are modified with discrete functional particles that are bound, or adhered to the filler particles, the filler particles being distributed evenly throughout the solid surface wherein (a) 95-99 volume fraction percent of the filler particles has a major dimension in the range of from 0.5 to no greater than 10 microns, (b) the D50 of the filler particles is from 0.5-2.5 microns, (c) the D90 of the filler particles is equal to or less than 10 microns and (d) the filler particles are modified with discrete functional particles that are bound, or adhered to the filler particles.
