CAS 1606-85-5 Butynediol ethoxylate
Butynediol ethoxy compound (BEO) CAS 1606-85-5 is a condensation product of butynediol and ethylene oxide. It is one of the commonly used long-term nickel plating intermediates, which refines the grain size of the coating. Usually used in conjunction with auxiliary Chemicalbook brighteners such as saccharin, PME, PPS, PVSS, COSS, PESS, or MOSS. A long-lasting brightener and weak leveling agent for electroplating nickel. Butynediol ethoxylate can refine the crystallization of the coating. Produced using high-pressure method and using physical methods for decolorization to reduce the damage to effective ingredients caused by chemical decolorization, it has the characteristics of light color, resistance to consumption, and strong leveling.
