PN-8 after-treatment auxiliary for silver plating

 

PN-8 is a kind of aqueous treating agent without solvent. The protective film which is formed by after-treatment auxiliary for silver plating on surface can improve the property of antitarnishing and anticorrosion. The wear resistance performance for metal will be also improved.

 

Properties:

1.It does not contain any organic solvent,and the protective film formed by it is avirulent and non-irritating, which is save and kind to environment.

2.The operation is easy: as the plating articles immerge into the PN-8, protective film will form quickly.

3.The protective film will hardly change the metal's contact resistance or weldability to tin.

4.Heat-treatment (300 below)in shot time does little affect to properties of protect film.

5.Plating articles do not tarnish before immerged into the 2% K2S in 3 minutes.

6.Plating articles do not tarnish before immerged into the 3% K2S in 2 minutes.

 

Composition of bath:

It can be put to use after diluting the concentrated solution of PN-8 at pure hot water,which is easy to operate.

Conditions of operation:

 

PN-8: 200 ml / L

 Temperature:  42 ( 40 - 45 )

 Immersion time:90 ( 30 - 180 )seconds

 

Replenishment of bath:

Maintain the liquid level by pure water.If you want to obtain perfect protective effect, PN-8's concentration should be kept at range of working concentration,which can be controlled by analysis method.
