Metal Deactivators

CUVAN® 303 Metal Deactivator

NSF Certified: HX-1, 138995 - CUVAN 303 is an oil-soluble corrosion inhibitor and metal deactivator for lubricants, greases, and metalworking fluids. As a corrosion inhibitor, it is effective in protecting copper, copper alloys, cadmium, cobalt, silver and zinc. As a metal deactivator, CUVAN 303 inhibits oxidation by chelating metal ions that catalyze oxidation. Recommended treat levels are from 0.05 to 0.20 mass percent.

NACAP® Corrosion Inhibitor

NACAP is a corrosion inhibitor for water, alcohol and glycol systems. Particularly effective in preventing corrosion of copper and brass. Widely used in antifreeze where it functions as a copper corrosion inhibitor and alkaline buffer. It is an excellent corrosion inhibitor for aluminum in systems where aluminum is used in the presence of copper and copper alloys. NACAP is one of the standard copper corrosion inhibitors for the anti-freeze industry. Used as a chemical intermediate.

VANCHEM™ NATD Metal Deactivator

VANCHEM NATD is a corrosion inhibitor and metal deactivator for nonferrous metals in aqueous systems. VANCHEM NATD is suggested particularly for protecting solder, aluminum, copper and copper alloys. It is stable and active at lower pH values than many mercapto compounds. VANCHEM NATD as a chemical intermediate is a stable reactive dimercaptide which is readily alkylated, oxidized to the disulfide, or converted to metal salts.

VANLUBE® AZ Lubricant Additive

VANLUBE AZ is used in engine oils, in industrial oils, and in soap and clay-thickened greases. Used in both gasoline and diesel crankcase oils to inhibit oxidation, bearing corrosion and wear. Used in combination with detergents, it inhibits corrosion and wear by inhibiting oxidation of the oil and also by the formation of protective films on metal surfaces. Used as a partial replacement for zinc dithiophosphates. Because of its effectiveness at high temperatures, it is a good additive for crankcase oils in heavy duty service. In industrial oils and automatic transmission fluids it functions as a high temperature oxidation and corrosion inhibitor. Used in lubricating greases both as an oxidation inhibitor and metal deactivator. An excellent copper corrosion inhibitor of the film-forming type.
