I'm loathe to use straight NaOH or KOH as a developer because I would prefer to have a buffer when developing. As I want to be able to use this in a spray etcher I am building, a buffer would be really helpful.
I've never been able to find silicate developer solution so that leaves me with making it as the only alternative (and that's fine- I'd prefer to understand what's going on anyway). That said- can anyone explain the chemical processes at work during developing?
I've read the Moorshead recipe but without understanding what does what- it just seems arbitrary. It seems like a regular NaOH developer with sodium silicate as a buffer and nothing else. Is it that simple? The silica developer sold by Rapid Electronics does not contain NaOH so I suspect it's a very different animal.
Any help would be appreciated.
