In 2008, Epner Technology, Inc. was chosen to provide their Laser Gold coating on thermal barrier foil in order to efficiently reflect engine heat in the DiMore Motorcar’s $2 million Natalia SLS 2 sport luxury sedan.
Most automobiles use a metal firewall to insulate the passenger compartment from the heat generated by the engine. Instead, the Natalia firewall will be a lightweight composite fiber panel. This will be covered with the Epner protective film that features a pure gold surface on the engine side. The gold reflects infrared heat away from the passenger compartment. At one-third the thickness of a human hair, Laser Gold coated foil forms a virtually impenetrable barrier to the blistering heat generated by the 1200-horsepower Volcano engine. It combines the high infrared reflectivity of pure gold with the hardness of an alloy.
