Looking for high emssivity at 400deg.c materials
(OP)
Want to use it as a target cover for IR detector emissivity calibration of metals at the same temp.
Can be paint or tapes,
thank you

> "Black" gold, which is a coating used primarily in LWIR to reduce reflectivity. It's essentially a non-dense deposition that counts on tortuous-path absorption.
> Physical means, A surface coated with black gold or even possibly a roughend anodized aluminum with cavities. The cavities would be pyramidal with perhaps a 4 or 5 to 1 aspect ratio.
> Some sort of "carbon black" or soot coating.
> EOI has a proprietary coating that's used in some of their blackbodies (look for "EOI Mid temperature"):

I have "been there", no info where to purchas the paints, are they std.?
KIKRON CO. has a special test paint with E of .99
