COPPER CHLORIDE & PVDF Compatibility

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.

PVDF temperature limit: 275°F (135°C). That is Arkema’s maximum use temperature for Kynar Flex® 2850 PVDF, the resin we mold, with Copper Chloride (Aqueous solution or solid). Arkema’s limits are for solid resin at atmospheric pressure and do not account for mixtures. Source: Arkema Kynar® PVDF chemical resistance chart. Confirm your application with Bailiff before ordering.
