COVENTYA develops and supplies engineered chemicals for use in electroplating and surface technology, and in water treatment processes. As part of a demonstration project, COVENTYA supplied the application chemicals and the zinc-nickel membrane system (PERFORMA 285 PMS) used in a barrel plating unit. (s. CPG Project: Resource eficient Zn/Ni electroplating process)

Dipl. Ing. Herwig GmbH is a supplier of degreasing agents, fluxes, inhibitors, zinc alloys, and zinc purifiers mainly for use in the hot-dip galvanizing industry. The company developed a flux recycling system (Fluxomat) and the “Hegaflux Ferrokill” flux, which were used in a demonstration project as environmentally friendly components of flux treatment. (s. CPG Project: Reduction of zinc consumption in the hot-dip galvanizing process)

Enthone develops, produces and sells decorative surface coating processes. As part of a demonstration project, an Enthone product (ANKOR Wetting Agent FF) was used as a PFT-free wetting agent in a plastics electroplating facility. (s.
