[vc_row][vc_column][vc_column_text]NeroSuperior is a high-performance technical surface coating<\/strong> developed by Eurogalvano, designed to provide high corrosion resistance, surface hardness, aesthetic stability<\/strong>, and improved tribological properties.
\nThe treatment is suitable for both functional and decorative applications in advanced industrial and technical sectors.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n

Technical Characteristics<\/h2>\n

Corrosion Resistance<\/h3>\n
    \n
  • High protection against atmospheric and chemical agents<\/li>\n
  • Superior performance compared to many traditional black nickel coatings<\/li>\n
  • It does not require oiling or transparent protective varnishes but can also be painted glossy or matt.<\/li>\n
  • It is available in pearl versions (from 3Q7 to Classic Perla)<\/li>\n
  • Intrinsic stability of the coating (Salt spray resistance values available on request depending on the applied cycle.)<\/li>\n<\/ul>\n
