Nickel Plating Bath Chemical Solution

Nickel plating bath chemical composition should be included of satin finished chemicals in order get a brighit surface after plating. Beside a nickel salt that usually use Nickel Sulfate, also contain of an alcohol soluble polyamide resin and polishing agent disolved in bath alltogether. The polyamide resin is a member selected from the group consisting of a copolymer of dimer acid and an aliphatic amine, a copolymerized nylon and a modified nylon. The electroplating bath preferably contains a cationic surface active agent selected from the group consisting of an aliphatic and/or aromatic quaternary ammonium salt and an aliphatic and/or aromatic fluorosulfonylamine quaternary ammonium salt. The use of the electroplating bath provides a means for obtaining a uniform satin-finish nickel plate surface on the material plated.

Chemicals plating solution of acidic nickel electroplating bath contain of a uniform satin finish metal plate surface on the material plate surface as below:

1. Nickel 25 to 170 gm/lt
2. Polyamide resin disolved in low molecularweight and alcohol have 1 to 3 carbon atom: 1 – 10,000 ppm
3. Polishing agent: 0.1 to 40 gm/lt

Nickel is dissolved and forms a continuous aqueous phase solution and polyamide resin is dispersed in aqueous phase to form a stable emulsion.
