Beneq solution

Beneq’s patented nSilver industrial-scale protection solution provided an ultra-thin, totally conformal, and fully transparent anti-tarnish coating. nSilver is based on atomic layer deposition (ALD), a coating technology that enables the growing of thin films on articles of any shape. The coating is pin-hole free, and extremely uniform over the entire batch of coated articles.
