1,4-BIS(2-HYDROXYETHOXY)-2-BUTYNE - Upstream Downstream Industry

Raw Materials2-Butyne-1,4-diol

1,4-BIS(2-HYDROXYETHOXY)-2-BUTYNE - Electroplating intermediate

1. Butynediol ethoxy compound (BEO for short) is a condensate of butynediol and ethylene oxide. It is one of the commonly used long-acting nickel plating intermediates to refine the coating grains;
2. It is usually used in conjunction with auxiliary brighteners such as saccharin, PME, PPS, PVSS, COSS, PESS or MOSS.
3. Long-acting brightener for nickel plating, weak leveling agent.
4. butynediol ethoxylate can refine the crystallization of the coating. It is produced by high-pressure method and decolorized by physical method to reduce the damage of effective ingredients by chemical decolorization. It has the characteristics of light color, consumption resistance and strong leveling.
