Copper Chloride (cupric chloride, CuCl2, CAS 7447-39-4) is usually stored as a green to blue-green acidic solution. It is corrosive and very toxic to aquatic life. Cupric chloride is used as an etchant for printed circuit boards, as a catalyst in chemical synthesis, in wood preservatives, pigments and textile dyeing. Spent etchant is commonly collected for copper recovery, and containment helps prevent releases. Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
Polypropylene is the most economical tank material for Copper Chloride, rated Excellent. PVDF (Kynar®) is also rated Good or better. Avoid nylon tanks; 316 stainless steel and titanium hardware.
