Hi Hexavalent,
Absolutely not. The Sands SDE3008 works as a green sensitizer even when it is the last component added to the make(with at least 15 minutes mixing.)..
The reason that I am working to find an alternative dye is COST. The SDE3008, like the red sensitive SDA3057 is just too expensive. All my emulsions are Br/I.
