Dow Develops Chromium-Free Etch for Sustainable Plating on Plastic Manufacturing

Enabling REACH Compliant Plating on Plastic Ahead of the Sunset Date

Philadelphia - December 08, 2014

Dow Electronic Materials, a business unit of The Dow Chemical Company (NYSE:DOW), has developed a novel chromium-free ECOPOSIT™ etching solution to replace chromic acid etching used in the pre-treatment of Acrylonitrile Butadiene Styrene (ABS) and PC-ABS in the plating on plastics (POP) industry, to help manufacturers to meet the September 21st 2017 sunset date set by REACH to eliminate the use of chromium trioxide. 

The selection of a replacement etchant species was the result of many years of research to find a candidate and associated process parameters, with the stability, performance and process window to substantially fit into existing POP equipment. Dow’s novel ECOPOSIT™ Etch becomes an integral part of the ECOPOSIT CF-800 Chrome-Free pre-treatment, utilizing the stable and regenerable MnIII species to replace the incumbent hexavalent chromium oxidant. Dow has been granted a US patent for this novel chrome-free etch (CFE), laying the platform for the move towards commercialization and the road to the elimination of hexavalent chromium in POP pre-treatment.

“Dow Electronic Materials’ investment in sustainable technology is evident in this novel POP development,” said JR Chen global business director at Dow Electronic Materials, “Dow continues to invest in value added products as our customers face many challenges in support of the increased performance demands, whilst being safer for people and the environment”

The building of industrial performance data in different market segments has begun in order to provide pathways for customers to test and qualify Dow’s technology and implement in advance of the 2017 deadline.
