What is the meaning of "BZT" in the formula for Agfa Neutol WA Paper Developer?
Probably benzotriazole. Cheers, DJ
Thanks DJ for your info. The formula listed on this website specified a liquid measure i.e. 10ml., whereas the supplier I contacted stated it was a powder only!
Ron - Usually people work with a 1% solution of benzotriazole and add 10ml of the 1% solution in the formula. This is commonly done where there is a requirement for a small amount and measuring it in powder form would be difficult.
Check other sources for the formula to see if others define it as a 1% solution.
Can you please provide a link to the formula? Thanks, Jim.
Found the thread, although I though the formula was proprietary and therefore unpublished.
Ron,
you might want to look here.
following the links around the site for Benzotriazole you should find that in small amounts (10ml of 1%) it works as an antifoggant. In larger amounts it works to neutralise or cool the image tone)
In metal applications it basically works as a rust(oxidation?) inhibitor.
Thanks guys for all your contributory info about "BZT">
