Legor® GT4PINK heavy-deposition solution allows you to plate workpieces with a deep rose color that is actually 18 karat and up to 5 microns thick. Because the solution is acid-based (the first acid-based rose-gold plating solution) rather than cyanide-based, maintaining the bath over time is as easy as it is for other acid-based gold solutions. This solution is especially ideal for decorative plating applications that require a hard gold or greater thickness (up to 5 microns) with dependable color. The gold in the solution is co-deposited with copper, generating an alloy that is 75% 18K. Contains 4g 18-karat pink gold.
