In 1994, NASA patented Protective Coating for Ceramic materials (PCC). This high emissivity coating was developed to be used as part of the heat shield for the next generation of Space Vehicles, the X-33 and X-34. Wessex Incorporated of Blacksburg, VA obtained an exclusive license for PCC excluding aerospace applications and went on to develop Emisshield Coatings.

Ventech Industries of Eliot, Maine has teamed with Wessex Inc to form Dynacote LCC and bring the Emisshield Coatings to the fireplace, chimney, barbeque, stove, and accessory markets.

Emisshield Coatings are able to offer their many benefits because they are high emissivity nanoparticle ceramic coatings; improving the transfer of radiant heat.

Dr. John Olver was quoted as saying this product showed promise for "any application where heat, wear and thermal degradation are factors." He went on to say that after 10 years of testing and refining this product, the potential is endless.
