Solid surface material
Solid surface material, also known as solid surface composite, is a man-made material usually composed of a combination of alumina trihydrate (ATH), acrylic, epoxy or polyester resins and pigments. It is most frequently used for seamless countertop installations.
A solid surface material was first introduced by DuPont in 1967 under the name of Corian. Since the expiration of their patent other manufacturers have entered the market with their own branded products. These include Krion® by Porcelanosa Grupo, HIMACS by LX Hausys, Hanex Solid Surface by Hyundai L&C, Staron by Lotte Chemical and Velstone.
