-----Iridite Process
We are to develop an Aluminum heat sink with Yellow / Clear Iridite coating. Please can you give me some detailed stats of this Iridite process so that I can develop it here. The parts are small - 4" X 4". Please let me have some details on this process.
Thanks,

"Iridite" is a Macdermid brand name, so you certainly cannot formulate it yourself. But you are probably really referring to generic chromate conversion coating. You will find SOME details if you do a literature search back in the early 1950's when the process was developed; these days it's proprietary knowledge.

There is also a pretty good article on Chromate Conversion Coating in the Metal Finishing Guidebook at www.metalfinishing.com. That would be a smart place to start, then finish by talking to a vendor of the materials.
Good luck!

I need to know if there is a way to coat an area that needs rework on aluminum parts if it needs to be re-machined, like a hole needs to be opened up.What can I do to coat the hole

A. Chromate conversion "pens" are available from most of the suppliers of chromate conversion chemistry, Cecil.
