The hindered bisphenol antioxidants, while useful for minimizing staining, can present problems in some formulations. For example, milled stocks containing some hindered bis-phenols such as Santowhite Crystals (Monsanto) have relatively short bin stability. On aging, for as little as one week at 38 C (100°F), the stock may not make a smooth solution. If the stocks are dissolved within two or three days of milling, no problems are normally encountered. Antioxidant 2246 (American Cyanamid) has been known to create color problems a pink discoloration in latexes, a bluish or blue-green discoloration in some solvent systems, particularly those based on chlorinated solvents.
