My company manufactures electronics rated for space applications. We are considering using a vendor supplied heatsink that has the following finish "Black Ebonol C". I have been unable to find documentation of this finish in regard to any industry standards (MIL, ASTM, etc) that cover such a finish. I would like to determine what standard this finish meets, exactly what it is composed of, and is it approved for space applications (low outgassing, TML, etc)?
Thank you in advance for any assistance you can provide.
