APPLICATIONS of Golpanol PS:
Golpanol PS is an intermediate used in production of brightening additives for electroplating in bright Nickel plating baths.
Golpanol PS acts as a Class I & Class II brightener and promotes throwing power, clarity, low current density area brightness and levelling.

Golpanol PS is used to formulate brightener additives employed in the electroplating industry. 
Golpanol PS is employed as a top brightener and levelling agent for electroplated nickel at concentrations of 5 - 150 mg/l.

Applications of Golpanol for nickel electroplating
Golpanol products are special additives for nickel plating. 

They are used besides others for decorative applications. 
In chrome plating the chrome layer itself is very thin. 
The subjacent level is nickel as the primer layer providing brightness.

STORAGE CONDITION of Golpanol PS:
Golpanol PS has a shelf life of one year in its sealed original packaging, provided it is stored properly.
