Anti-tarnish Process Reduces Precious Metal Use for Decorative Products

The anti-tarnish 616 Plus organic nanotechnology process from Uyemura preserves metal brightness of yellow gold, rose gold, silver, copper and tin indefinitely for reductions in precious metal use. Engineered nanopolymers absorb on the metal surface, crosslinking to form an invisible, undetectable layer. It also seals thin gold’s inherent porosity. By penetrating the grain structure, it prevents oxidation of the underlying nickel or copper so that when gold is applied, plated parts have exceptional corrosion resistance. The process technology is ideal for high-end jewelry, handles, rivets and decorative components.

The company also offers its Nanofics coating for long-term water and corrosion resistance for components and subassemblies or to encapsulate complete boards.
