Product group of Antitarnish processes 328, 613 and 614 extended by the skin-friendly Antitarnish 615.

This process is a medium based on nanotechnology for protecting gold, silver, rhodium, platinum and palladium against tarnishing. Treated surfaces are protected from tarnish effects for a prolonged period. A thin, invisible protective layer is applied by simple immersion in the metal-free antitarnish based on ethanol. This layer protects the basic material from oxidation and discoloration without adversely affecting the solderability.

Antitarnish 615 for rack and barrel applications is kind to the skin and do not cause any allergies. It additionally protects against scratches and abrasion and is dirt and water repellent. Subsequent treatment or repair by grinding and polishing is not impeded. The coating is inconspicuous and the precious metal remains recyclable.
