1. Feature

1. Cobalt content is low,the plating layer is non-magnetic.

2. Less wasted by water-out and better cost than traditonal process.

3. Bath is stable, pH (9-11) changed little, metal ions of tin and cobalt will not be decomposition and precipitation.

4. Can use in barrel or rack plating, color can be adjusted from light to dark, more black than common nickel-free gunalloy color.

5. Without potassium pyrophosphate, Low viscosity, low water consumption.

2. Conditions and Compositions of Bath  

3. Operation to Start-up The Bath

1.The start up only to use the GM-L Make-up Liquid directly, without any other additives in the begining. 

2. Test the Ph value after heating to 35℃, and then for trial production.

3. Plating time requires 8-15 minutes, 10 minutes is the best.
