Inhibitor Protection

Classified as six months protection when stored outside and properly protected from moisture and other environmental elements; 24 months minimum, inside dry storage.
Metal Corrosion Protection
Mild Carbon Steel Provides full protection
Aluminum (1100) Compatible, light protection in contact and vaporphases
Zinc or Zinc Galvanized Steel May provide light protection
Copper Compatible
Brass 1 Compatible
Bronze Compatible
Silver Not recommended 4
Category A 2 Not recommended 4
Category B 3 Not recommended 4

1 Brass alloys in the “red” area containing up 20% zinc will act like copper; brass in the “white” area containing over 20% zinc and will act like Category A metals 2 Category A metals include zinc, cadmium, nickel, cadmium-plated steel, and nickel-plated steel. These are prone to contact corrosion sensitivity with inhibitor chemicals, but will be protected as shown in the vapor phase 3 Category B metals include lead, antimony, Babbitt alloys, solder, magnesium or magnesium alloys 4 “Not recommended” does not indicate incompatibility. Compatibility testing is always recommended. Our “not recommended” rating indicates that there may be more effective products for these applications.
