We are specifying the new TCP conversion coating for some alumium parts and we have always specified "gold" color to our CR(6) coatings. I understand adding dyes to TCP makes it fail salt spray tests. We don't need a lot of protection since the end product is used in laboratory conditions...
Thanks kenvlach,
I will keep this info in case my vendors have a question on where to get the non cr6 dyes. I changed my specs to say: "Type 2 Class 2 (red) using non cr6 processes and dyes" This should cover everything.

We have some anodized parts that are currently being specified with "Type 2 class 2 (red)"
I understand that sulfuric anodizing has no RoHS issues, only the sealers. How should I specify the RoHS compliance?
Suggestions I already have are: "Type 2 class 2 (red) using non Cr(VI) processes."...
