Anti Tarnish Coating and E-Coating
Anti Tarnish Coating is a medium based on nano-technology for protecting silver against tarnishing. Special nanopolymers absorb on the silver surface and cross-link to form a protective layer of a few nanometers thickness. The invisible layer protects the base material from oxidation and discoloration.
The e-coating is infused with nano-ceramic particles which are undetectable by the human eye. These particles make the coating more abrasion-resistant than traditional coatings and they provide a metallic sensation to the touch. The metal underneath will remain perceivable and bring the advantages of antitarnish, Biologically safe, skin-friendly, and hypoallergenic.
