Seeking: Printable electrical heating element or film, bonded to metal surface

This organization is interested in licensing or supply of materials that can be printed, sprayed, or transferred onto a metal surface (e.g. copper, stainless steel, brass, aluminum, nickel, chrome) as a film, such that, when connected to a power source, the material gets hot and heats the metal surface to > 200 C (~400 F). The heating film or coating may be composed of several layers.

Heating element must be thin (<1mm), directly bonded to the metal, and must be able to withstand multiple heating/cooling cycles without delaminating from the metal surface. Heating of the metal sheet to temperature will be rapid, and even. Technology must be protected by filed or issued patents.

They have tried Kapton film heaters — however, they desire direct contact with metal surface for greater heat transfer efficiency and even surface heating.

Possible solution areas for this need include aerospace, the coatings industry, ceramics, and metallurgy.
