EPi is proud to offer finishing solutions that eliminate the use of cyanide. Since 1992, the E-Brite 30/30 alkaline non-cyanide copper process has eliminated cyanide in many plating facilities.

The resulting copper plate is finer and denser than cyanide copper. EPi's customers have reported plating 10–30% less copper plate than with cyanide copper. E-Brite 30/30 is Boeing-approved for commercial and space defense, Spec 5722.

Plates frequently use cyanide zincate, cyanide copper, and cyanide silver to plate on aluminum. EPi provides solution that allow metal-finshers to stop using cyanide by switching to one of three processes: the E-Brite Ultra Cu (alkaline non-cyanide copper), the E-Brite 50/50 (alkaline non-cyanide silver), or the E-Prep 280 NCZ (non-cyanide zincate).
