Tarnish Silver Pronice Aqua, NanoCraft Coating

Based on Smart Coating technology and using state-of-the-art nanoanalytics, the highly effective and successfully established pronice aqua silver tarnish protection was developed. The ultra-thin and invisible silver protection system has been optimised for industrial series production. pronice aqua is distinguished by its high protective effect against oxidative and mechanical stress, in combination with fast and simple process control. The delivery takes place as 1:100 concentrate. Fields of application: Jewellery manufacturers (industrial), electroplating, decorative and technical silver surfaces.

Tested Quality

The left chain was protected by means of pronice aqua – the right chain by means of conventional protection as known in the jewellery industry.

Both test chains were stored under the same conditions in very concentrated sulphur solution.

A considerable difference can be recognised due to the impact of the anti-tarnish protection. The pronice aqua treated test chain shows no discoloration at all.
