NACAP^®
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.

          ROKON^®
Used at 0.5 to 5 lbs./1000 bbls. as copper corrosion inhibitor in fuels containing corrosive sulfur compounds. Copper corrosion inhibitor or deactivator in numerous industrial lubricants such as heavy-duty cutting and metal-working oils, hydraulic oils, and lubricating greases. A corrosion inhibitor in automotive chemicals, industrial cleaners, and various chemical specialties requiring copper deactivator.

          VANCHEM^® NATD
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.
