| 1. Butynediol ethoxylate (BEO for short) is the condensation of butynediol and ethylene oxide, is one of the commonly used long-lasting nickel plating intermediates, so that the plating layer grain refinement; 2. Usually need to be used in conjunction with the auxiliary Chemicalbook brightening agent such as saccharin, PME, PPS, PVSS, COSS, PESS, or MOSS, etc. 3. The long-lasting brightening agent of nickel plating, weak leveling 4. Butynediol ethoxylate can make the plating layer crystallization fine. It is produced by high pressure method and decolorized by physical method to reduce the destruction of effective ingredients by chemical decolorization, and it has the characteristics of light color, consumption resistance and strong leveling. | |||||||||
