Blue/Iridescent Cobalt-Free Trivalent Passivate for Alkaline Zinc
LANTHANE 317 CF is a thick layer passivate for electroplated zinc surfaces. LANTHANE 317 CF forms a uniform clear yellowish film. The passivate is applicable for zinc deposits from acid and alkaline cyanide free electrolytes.
LANTHANE 317 CF works on the basis of trivalent chromium compounds and contains no cobalt or any other CMR substances. Brightness and colour of the passivated parts are very stable even after heat treatment (3h/210°C and 24h/120°C). The temperature stability is generally better on acid zinc.
Features & Benefits
- contains no hexavalent chromium and no cobalt
- low zinc dissolution during passivate process
- for rack and barrel application
- very good on acid zinc parts
- very economical in consumption
- long bath life due to inhibition of iron dissolution very stable colour after heat treatment
Fields of application

- Electrical equipment
- Electronics and collectors
- Furniture
- Leisure equipment
- Wire goods
- General industry
