Hi, Ravi. TCP is an acronym for trivalent chrome process, a Mil-C-5541 approved process for trivalent chromate conversion coating of aluminum. It was developed by and is approved by NAVAIR, and there are four suppliers who have been licensed to produce it.

It is supplied in different forms by the licensees, so you need to consult their technical data sheet for operating instructions like controlling the pH. I don't understand what you are looking for when you ask for "all the filtration techniques". Please describe your own situation before asking any followup questions. Thanks!

Regards,

Ted Mooney, P.E.
