Matt Black Finish Required

Can anyone assist me on finding a matt black finish that is RoHS compliant, and has no infra red reflectivity. We are getting lots of enquiries for so surely there must be either a supply house or finishing house that can offer this. Zinc & Black passivate is not an option, the base material can be of any substrate. We have looked at matt Anodise & Dye Black which has also proved to be unsuccessful as have any paints that react with cyanate based glues. Any Ideas would be much appreciated ?

Can the base material be titanium? If yes, we have a proprietary technology of titanium blackening. Non-reflective matte black was achieved for some NASA applications. We have also produced stainless blackening, however it was not durable in a long run.

Have you tried or looked at Black Chrome Plating? This may be an option?

There are infra-red absorbent paints available on the market. These can be applied to any substrate you like (assuming that it has been pre-treated properly). Try talking to the likes of PRC-DeSoto or AKZO, they may be able to help.
