Find out about the history and advantages trivalent chrome alternatives provide over existing hexavalent chrome chemistry for manufacturing, health and the environment.

About the European Mandate

The European parliament has added an annex to its reach legislation. Included in this is the production of decorative components plated in hexavalent chrome solutions. With this approaching implementation, effective date September 21st 2014 and a sunset date of September 21st 2017, all decorative plating shops in Europe must change to trivalent chrome solutions.

Likewise, all companies that export finished goods into Europe are subject to adhering to the mandate as the law maintains that all finished goods be free of any coating containing hexavalent chrome. Global finishers and manufacturers alike are significantly impacted by this mandate regardless of their direct presence in Europe.

Why Use Trivalent Chromium Chemistry?

Environment – Trivalent chromium solutions have no impact. Plated chrome is Cr0 but hexavalent chromium solutions are extremely toxic to the environment.

Health – Hexavelent chromium in both its hydrated and dehydrated state is extremely hazardous to health. Hexavelent chromium is rated as a CMR hazard level chemical meaning it is carcinogenic, mutagenic, and reprotoxic.

Color - Historically one of the main problems with earlier Trivalent chromium solutions, alternatives now exist in trivalent chrome technology that grant a near exact color match of hexavalent chromium.

Costs – Although trivalent chromium processes appear more expensive than hexavalent chromium, finishers actually realize savings when considering factors such as power, waste treatment and productivity improvements.
