We usually use trivalent chromium black galvanizing passivator to obtain a black and oily appearance with special decorative features. However, when using a black zinc passivator, the workpiece is prone to coloring and streaking, which affects the quality of the workpiece. For this reason, today we would like to introduce a trivalent chromium black zinc passivator BZ-216, which is not easy to be colored and has no flow marks.
1, BZ-216 black zinc passivator is environmentally friendly, completely free of hexavalent chromium, in line with ROHS environmental norms, is specifically used for trivalent chromium black passivate on the galvanized layer.
2、After passivation, the appearance of the workpiece is black and bright, with strong adhesion after drying, and no discoloration or peeling for a long time.
3、Good corrosion resistance. When BZ-216 is used together with sealing agent, it can get deep black bright appearance, neutral salt spray test is more than 96 hours.
