K2O ? H2O. Two other yellow chromate pigments are strontium chromate and barium chromate, both used as corrosion inhibitors. Uses Zinc chromate is used in pigments, rubber, linoleum manufacturing, metal surface treatment, electroplating intermediates, research and development. It finds its application ...

a range of zinc electroplating including Type I without supplementary treatment, Type II with supplementary colored chromate treatment, Type III with supplementary colorless chromate treatment, Type IV with phosphate conversion treatment, and Type V with supplementary colorless or colored passivate treatment...
The development and features of chromate-free passivation for Zinc coating are summarized. Point out that as the environmental protection become stricter, future research in Zinc coating passivation will focus on the transition from chromate passivation to low toxicity or non-toxicity passivators, especi...
Q. I cannot get a straight answer -- Zinc plating, zinc plating with chromate, Type II, III, etc. All I need to know is what color the types are. Here we use clear & yellow zinc plating ... also use the terms bleached and unbleached -- which I haven't heard of until I got ...
The new finish is now widely called trivalent chromating but it is very different from the old trivalent chromates; it has much greater corrosion resistance and it doesn't really have a natural blue nor yellow color (sometimes a faint brown). Most of the new trivalent chromating is highly ...
