Anodize


(2000)

I'm looking for a liquid that can be applied then rinsed or wiped off, to be baked to 150 C, later in the process. Is there such a liquid?

OKAY, OKAY, YOU JOKERS, the answer is "What are you trying to accomplish with this liquid? It is not anodize, it might be a chromate conversion coating, which can be applied to aluminum with a brush or a rag.

Baking to 150 C might be a bit too high to preserve the corrosion protection properties of a conversion coating.

Hey! Is there anyone who knows what chemical can make the aluminium surface bright and shining after black anodize ?

Hi, Ong. If you've seen bright and shiny parts like that, they were almost surely bright and shiny BEFORE anodizing, not made bright after it. The brightening chemical is a mix of nitric and phosphoric acid and is called aluminum bright dip, but often it's done after mechanical polishing. Good luck.
