Corian is the brand name for a solid surface material created by E. I. du Pont de Nemours and Company (DuPont). It is the original material of this type, created by DuPont scientists in 1967. It is composed of acrylic polymer and alumina trihydrate (ATH), a material derived from bauxite ore. Its primary use is as a countertop/benchtop surface, though it has many other applications.
Dr. Donald Slocum, a DuPont chemist, is credited as the inventor of Corian solid surface in 1967. His name appears on the patent issued in October 1968. A “Space Age” material, the product has evolved since its invention and spawned many imitations.
Solid Surfacing is:
- Stain resistant
- Seamless: In the fabrication process, joints can be made invisible by joining the relevant pieces with Corian’s own color-matched two-part acrylic epoxy. The pieces are clamped tightly together in order to express any excess adhesive. After the adhesive dries, the area is sanded and polished to create a seamless joint. This seamless appearance is a signature characteristic of the material
- Repairable and renewable: Cuts and scratches can be buffed out with a Scotch-Brite pad or orbital sander.
- Thermoformable: Flexible when heated, Corian can be shaped and molded into generally limitless forms which can be used in commercial and artistic projects through a process called thermoforming.
Heat resistance: the material is heat resistant up to 100 °C (212 °F), but can be damaged by excess heat. DuPont recommends the use of trivets when the material is installed in kitchens.
Scratches: The material can be scratched, with scratches particularly noticeable on darker colors. Most damage or scratches are repairable, however.
