Anodizing Dyes

[madmachinst]

Need a good source for anodizing dyes say 5 gallons at a time. Don't mind powders or liquids.
My best experience with black was not using just the Caswells stuff alone, but also mixing in some of the RIT stuff, but they don't have an OD green. Anyone know where I can get OD Green RIT powder (or liquid) and OD green dedicated anodizing Liquid or powder DYE? Good price of course.
Thanks

Caswell is the gold standard here. Their black is black. the Rit is blackish purple.

I am sure rit makes a green if you are not that fussy.

I don't know beans about anodize dye but I sure don't like parts that turn purple in sunlight. The stuff has to be stable over time and environmental factors, or you'll get complaints.

Yeah, UV resistance should be one of your primary criteria. Most red dyes in particular are especially "fugitive" when exposed to sunlight.

I like to mix both together. That's because regarding the black that is what got me the best results.

I’ve had thousands of dollars worth of parts ruined by anodizers with this attitude. There are many many black anodizing dies. RIT isn’t one of them. Just google anodizing chemicals.

I didn't ask for chit chat comments, I asked for a good source of anodizing dye of which, Caswell's alone, didn't give me good results. your comments sir are not constructive to my original question. just Google anodizing chems is not helping either.

Well I at least I did try to steer you out of the textile department.

kingscote chemicals gives out samples and has OD green. lets see if their sample is big enough, or at least any good. As I grow will need more. found a source for the Rit too. Like I said I use a culmination of both items. I get better results at least with black ( they say black is hardest to anodize, need biggest pore size to have a decent uptake of dye) and results are nothing to be argued with.
