instant gold plating materials for jewelry (neutral and cyanide-free)
Color: normal yellow and lemon yellow
Application: bathtub uses
Description of the process
AURUFORM YELLOW-P and AURUFORM LEMON-P electroplating products are powder or solution (neutral and cyanide-free) for instant (flash) gold electroplating, which have normal yellow and lemon-green tonality. Since these processes are instantaneous, they create thicknesses of less than 0.25 microns in the deposited gold layers.
Working conditions for using AURUFORM YELLOW-P and AURUFORM LEMON-P products
AURUFORM YELLOW-P and AURUFORM LEMON-P powder products are in the form of two-component packages, first, powder number one is poured into 1 liter of distilled water at 60 degrees, and after its complete dissolution, powder number two is added to the solution. If using these products as ready solutions, pour them in polypropylene tubs (PP) or Pyrex containers and use according to the following table:
| parameter | unit | scope of work | The optimal amount |
| Gold concentration | (gr/L) | 0.8-1.2 | 1.0 |
| Free cyanide concentration | (gr/L) | – | – |
| pH | – | 6.5-7.5 | 7 |
| plating time | (Second) | 5-25 | 10 |
| temperature | (°C) | 40-60 | 50 |
| Voltage | (V) | 2.5-4.5 | 3 |
| Current density | ampere per decimeter | 0.5-2 | 1 |
| Plating speed | microns per minute | 0.05-0.15 | 0.08 |
