Hello members,
I'm doing my first (1 lb) batch of keyboard mylars and I'm needing some info.
I have mixed a 50/50 of Nitric Acid and Peroxide. I am using 200 ml of Nitric and 200 ml of Peroxide. When I place the mylars in the acid, some of the mylars turn from a silver/white color to a grey, while some others don't seem to change colors at all... or I'm not leaving them in the solution long enough.
So, my question is "What is the average time to keep the mylars in the acid solution?" I don't want to take them out too soon, and yet, I don't want to think it takes 5 minutes per mylar when I have many more to do.
Some of the mylars did turn black and I can see that they must be stripped of the silver, while some of the black mylars don't appear to change at all. I think those are the carbon ones.
I'll also post my results and my yields from this 1 lb batch. If I get it right the first time, I'll do at least 4 more 1 lb batches to get an average yield from 1 lb of mylars. I have about 60 lbs to work with right now.
[UPDATE]
I meant to add that the the Nitric I have is 69.5%. Do I need to add more Nitric to make it 55% Nitric to 45% Peroxide?
