Description
R·G-258 Weak Acid Zinc-Nickel Alloy Plating Process
Product Features

RG-258 is a weak acid zinc-nickel alloy plating process with nickel content of 12%–15%. It is specially applicable for:

  • Plating cast iron parts such as brake pads in automotive industry
  • Plating fasteners including screws, nuts and bolts
  1. Extremely high corrosion resistance, greatly improving the performance of conventional zinc coatings. Nickel content remains highly uniform across a wide current density range.
  2. Only mild complexing agents are used with no ammonia. Fast metal deposition initiation, excellent adhesion, high hardness and superior wear resistance.
  3. All additives of RG-258 fully comply with RoHS regulations, free of lead, cadmium, mercury, hexavalent chromium, PBB and PBDE.
  4. Suitable for rack plating and barrel plating.
