Plating Solutions- Cadmium- Cyanide Bath 90F & Polypropylene Compatibility

Cadmium Cyanide Plating Solution (90°F) is an alkaline electroplating bath containing cadmium oxide, sodium cyanide and sodium hydroxide, typically run at about 70°F to 90°F. It deposits a corrosion-resistant cadmium coating on steel fasteners, aerospace and military parts. The bath is extremely toxic, and contact with acid releases deadly hydrogen cyanide gas. Plating tanks must be kept separate from acids and have full secondary containment. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
