Pre-treatment: Surfactants
Complete set of electroplating intermediates (water-based/oil-based acid zinc, cyanide-free alkaline zinc, zinc-nickel alloy, nickel plating, chrome plating, acid copper, alkaline copper)
Sealers (water-based nano sealer, high-performance resin sealer, water-based nickel sealer)
Passivators (blue-white passivator, iridescent passivator, silver-white passivator, etc.)
DC, Sodium Saccharin (imported effect, price advantage)
Chromium-free passivator for lithium battery copper foil (passes oxidation resistance test after immersion for 2-3s)
Copper foil additives: SPS: improves tensile strength and ductility
