Patent ID: 10570280

Abstract:
A solid surface comprises (i) from 45 to 80 volume fraction percent of polymethylmethacrylate or unsaturated polyester or a combination of both, (ii) from 25 to 55 volume fraction percent of inorganic filler particles distributed evenly throughout the solid surface, and (iii) from 0.75 to 8 volume fraction percent of a siloxane fluid, wherein, when the filler has a major dimension of from 30-50 micrometers, the siloxane has a molecular weight of from 40,000 to 150,000 or when the filler has a major dimension of from 10-15 micrometers, the siloxane has a molecular weight of from 25,000 to 100,000 or when or when the filler has a major dimension of from 1-10 micrometers, the siloxane has a molecular weight of from 5,000 to 100,000.
