Substitution of Sodium Dichromate for Passivation of Electrolytic Tinplate (ETP)

Substitution of Sodium Dichromate for Passivation of Electrolytic Tinplate (ETP)

Type of measure: Substitution

One of the goals of the European REACH regulation is the progressive replacement of substances of very high concern (e.g. carcinogens) by safer alternatives. Companies that use these substances, actively search for safer alternatives (less dangerous substances, new technologies and processes), and report about these alternatives. Below you will find the information on possible alternatives for chromium trioxide, included in the different applications for authorisation received so far by ECHA. To obtain further details, please follow the link to the full dossier.

Below you can find possible alternatives for sodium dichromate for passivation of electrolytic tinplate (ETP).

Sodium Dichromate

  • EC-number: 234-190-3
  • CAS-number: 10588-01-9
  • Use: Use of sodium dichromate for passivation of ETP
  • Technical function: Stabilising agent

Most promising alternative:

  • Chromium Free Passivation Alternative (CFPA) (a Zirconium/Titanium Fluoride liquid solution system).
