| PROCESS | OPERATING CONDITIONS | APPLICATION | |
| ZINKON 781 | ZINKON 781 NITRIC ACID pH TEMPERATURE TIME | 50 – 80 ml/l AS REQUIRED 1.8 – 2.2 AMBIENT 20 – 60 sec | Clear blue trivalent chromium passivation. Three times better corrosion resistance as compared to hexavalent chromium passivations. |
| ZINKON 782 | ZINKON 782 NITRIC ACID pH TEMPERATURE TIME | 15 ml/l 4 ml/l 0.8 – 1.2 AMBIENT 10 – 20 sec | Produces yellow iridescent chromate layer over zinc plating for better corrosion resistance. Economical and easy to use and maintain. |
| ZINKON 783 | ZINKON 783 A ZINKON 783 B pH TEMPERATURE TIME | 80 ml/l 80 ml/l 1.2 – 2.5 AMBIENT 80 – 120 sec | Produces a uniform jet black coating. Good corrosion and abrasion resistance. |
| ZINKON 784 | ZINKON 784 TEMPERATURE TIME | 60 – 120 ml/l AMBIENT 30 – 90 sec | Produces olive green chromate conversion coatings on chloride zinc deposits. Stands corrosion resistance of over 200 hrs in salt spray. |
| ZINKON 785 | ZINKON 785 TIME | 50 – 80 ml/l 20 – 30 sec | Blue zinc passivation for on zinc coatings for better corrosion resistance. |
