BEO Application:

1. Butynediol ethoxylate (BEO) is a condensate of butynediol and ethylene oxide, one of the commonly used long-acting nickel-plating intermediates to refine the grain of the coating;

2. It is usually used in combination with auxiliary brighteners such as saccharin, PME, PPS, PVSS, COSS, PESS or MOSS.

3. Long-lasting brightener for electroplating nickel and weak leveling agent.

4. Butynediol ethoxylate can crystallize the coating. It is produced by high pressure method and decolorized by physical method, and reduces the destruction of effective components by chemical decolorization. It has light color, resistance to consumption and strong leveling capacity.
