Subject: [pure-silver] Diafine
Hi,
I've found out, much to my regret, that Diafine is no
longer available in Canada. I wanted to get some to
develop some 16mm microfilm that i have been shooting in a
Mamiya-16 and Minolta-16 II.
It is available in the US, at Freestyle and B&H. B&H
states quite clearly that they will not ship and that you
have to come to pick it up at the store; Freestyle tells
me that they can't ship Diafine to Canada because it is
considered a hazmat and there are to many obstacles and
too expensive to ship a hazmat.
I did a search in Google to see if the formula is
available; the chemicals I can get locally. But all I got
was several two part developer substitutes for Diafine but
not the actual formula. Is it some sort of state
secret???
Would anybody in the group have the formula for Diafine?
Cheers,
bogdan

The MSDS does not indicate any hazardous ingredients in

that it upsetting the canadians.
