Today’s zinc chromates processes have developed with zinc trivalent chromates to meet European Union initiatives. Trivalent chromates are much more environmentally friendly than hexavalent chromate processes. With EPi's innovation in trivalent chromate technology, EPi has met European Union initiatives such as the End of Life Vehicles (ELV) and restriction of the use of certain hazardous substances in electric and electronic equipment (RoHS).
