Chicago Albumen Works claimed previously on their Website that Kentmere made Centennial POP to their (CAW) formula. Now they say "Unfortunately, in the current economic climate, the cost of procuring the Centennial™ POP formula". Something doesn't sound right here.
As a new paper has only just been launched to replace Azo, it is possible to bring replacement products to market albeit made by a different manufacturer. But someone has to shoulder the R&D costs etc.
Like Ron (PE) and others I have a number of formulae for POP's but at present I don't want to return to emulsion manufacturer.
