Cortec G-6 Corrosion Inhibitor for Copper and Brass Alloys

Product Description

G-6, benzotriazole, is a proven corrosion inhibitor for copper and copper-based alloys. G-6 functions by reacting with surface copper oxides to form a strong, insoluble polymeric complex. This complex creates a protective layer or film on the copper surface, 10- to 20- molecule thick, that provides both a mechanical and electrochemical barrier against corrosive attack. This protective layer has a high degree of thermal and oxidative stability and cannot be easily removed. G-6 complexes copper ions in solution, thereby preventing galvanic corrosion of other metals in contact with copper.

Suggested Uses

G-6 can be used in many applications for protecting copper and copper alloys.

• Direct treatment on rolled copper or brass sheets and coils  
• Circulating cooling systems such as cooling towers and air conditioning systems  
• Functional fluids such as hydraulic fluids, specialty lubricants, automotive coolants, and metalworking fluids  
• Wrapping paper and box board for wrapping, interleaving, shipping and storing copper and brass items  
• Corrosion protective coatings such as lacquers and waxes  
• Cleaners such as soaps, detergents, and strong alkali or acid cleaners  
• Fabricated products made from copper and brass  
• Artifacts, sculptures, and decoration items

Dosage

G-6 is incorporated in liquids at a concentration between 0.1% and 2.0%. It has a near neutral pH at these concentration levels. Liquids may be either aqueous or non-aqueous. It may also be used as a solid or vapor. For a specific recommendation please contact a Cortec representative.

Packaging

G-6 is available in 5 pound (2.3 kg), 50 pound (23 kg), 100 pound (45 kg) fiber drums, and bulk.
