Drying Alodine CCC in aqueous solutions rather than in air stream




Dear members,

According to the Techology, freshly converted CCC should be rinsed in DI and then dried in the air at 50-60C. But in my case, this is rather complicated. It would be much more convinient to dry the CCC in an alternate way, just in the aqueous solution.

I do it in the following way. First, after rinsing, I fill the system with DI water and let it circulate for 1 week to allow CrO3 to nucleate in fine crystals. Then, I add increasing (doubling per day, starting from 10 millimoles to 67%) concentration of glycol (EG) which should suck water from the CCC and promote ageing.

What do you think about this way instead of classical air drying/ageing?

Thank you!
