ZINCATE 50 is a cyanide-free dilute zincate process for processing aluminum and its alloys. It removes aluminum oxide and applies a thin zinc film on the aluminum alloy by immersion to prevent its re-oxidation. This film can then be electroplated with copper, nickel and certain other electrolytic processes as well as with electroless nickel. The dilute ZINCATE 50 solution has low viscosity that rapidly penetrates the water film present on the cleaned aluminum. This new alloy process produces a denser, more uniform zinc film that improves adhesion to the aluminum, helping to insure excellent adhesion of the subsequent plate. This unique zincate film cannot be found with most other conventional zincates.
