June 11, 2008 While doing Zinc plate with Sodium dichromate finish, is it RoHS compliant. Sudhir Kulkarni Designer – Bangalore, Karnataka, India June 11, 2008 Hi, Sudhir. Dichromate is Cr2O7-2. The chromium is in hexavalent state and is forbidden by RoHS. However, RoHS-compliant “chromates” are widely available (I put “chromate” is quotes because they are called trivalent chromate but are not really “chromate” because that is chemically CrO4-2).
