Ben Wen has been granted a patent for a a bio-based coating comprised of polymerized oil made from oil comprised of triglycerides with unsaturated fatty acid chains, wherein the oil is free of petroleum; and, a catalyst mixed with the oil before it is polymerized, the catalyst is comprised of a thermochromic material comprised of one or more properties that:
Reduces the temperature for polymerization of the oil to create a suspension that forms a hardened mixture when cooled below approximately 100? C and switches the hardened mixture from transparent to reflective of infrared light when the temperature rises above a switching temperature in an approximate range of 18ºC -35ºC.
