Find High Emissivity Paint for Accurate Infrared Temperature Measurements

[bobbski]

I'm supposed to measure temperature with an infrared camera. But when used on materials such as gold and aluminum or iron I get false readings (the emissivity is low). To solve this problem I figured I would need a paint that gives the surface high emissivity (low-reflective).

My question is; where do I find this paint and what's it called

3M used to make a super black Solar-Absorbent coating years back, but I don't know if it ever went commercial, due to the nature of the volatile solvents.
