Antioxidants are organic compounds that retard autoxidation reactions, and they are added to polymer systems that have a tendency to oxidize and thermal degradation during high temperature processing, curing and storing as well as in end use. SONGNOX ® CS 1010 and SONGNOX ® CS 1076, the most commonly used phenolic antioxidants, guard against thermal degradation over a broad range of temperatures in numerous different coating, adhesives and sealant applications. For coating systems that are cured or stored at high temperatures, as required for powder and coil coatings for example, secondary antioxidants such as SONGNOX ® CS 1680 and SONGNOX ® CS 6260 as phosphite antioxidants are the best candidates.
