Thermal insulating coating

Thermal insulating coating

Thermal insulating coating

(OP)
Does anyone know of a good coating to prevent convective cooling.  The material that I am trying to insulate is copper.  The application is a cold plate on a thermoelectric cooler.  The parisitic heat load is too high an my efficiency is suffering.

Thanks

RE: Thermal insulating coating

There are some "hitech", ceramic based coatings designed to provide insulation for gas turbine hot section components. These coating have also been used in the automotive/motorsports applications. They are designed for temperatures up to 2000F or more. You may be able to get by with an insulating paint. There are a few manufacturers our there. Sorry I do not know any names off the top of my head. Try a web search for "insulating paint".

RE: Thermal insulating coating

You might get a better search under "Thermal barrier coating" or TBC.  There are plenty out there, some more exotic($$$) than others, some are two parts (metallic undercoat, ceramic top).
