Sodium Tolyltriazole 50% (Mid South TT50S)

Copper, Brass, and Multi-Metal Protection


Mid South TT50S (Sodium Tolyltriazole 50%) is designed for use in open cooling tower and closed recirculating systems to inhibit corrosion on copper, copper alloys, and other metals. Mid South TT50S functions by reacting with copper oxide on the surface of copper or copper alloys forming a strong, insoluble polymeric complex. This complex formation results in a protective layer or film on the copper surface, a few molecules thick, that provides both a mechanical and electrochemical barrier against corrosive attack. Also Mid South TT50S is chemically stable when introduced into highly alkaline or acidic systems and varying temperature conditions.
