Dow Electronic Materials, a business unit of The Dow Chemical Company, offers its chromium-free Ecoposit etching solution to replace chromic acid etching used in the pretreatment of Acrylonitrile Butadiene Styrene (ABS) and PC-ABS in the plating-on-plastics (POP) industry. This solution is intended to help manufacturers meet REACH’s 2017 deadline for eliminating the use of chromium trioxide.

This etch is part of the Ecoposit CF-800 chrome-free pretreatment, utilizing the stable and regenerable Mn III 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 pretreatment.
