“I need to “paint” some electronic housings that are supposed to also function as heat sinks. What would be the best powder type to use for such an application? The best thermal conduction and heat emissivity properties are what I am looking for. Can you please help?”

“Most thermoset organic powder coatings will not conduct heat as well as an uncoated part. Therefore, you can assume that all these coatings can be considered thermal barriers to some extent. The most important issue is not which coatings are best for this application, but rather which color and what thickness the coating should be. For instance, black is the most appropriate color for thermal transmission. It shouldn’t be applied more than 2.0 mils thick.”
