electroplating intermediate | 1. pyridyl hydroxypropane sulfonate (PPSOH) is an excellent nickel polishing agent intermediate, high leveling agent for nickel electroplating; It has the same leveling property as PPS, and has good leveling performance in the middle and low regions. 2. PPSOH also has excellent low current density zone displacement capability and needs to be used in conjunction with BEO, PME, PESS or MOSS, saccharin and auxiliary brighteners. 3. the central control index is adopted to control the reaction degree, and the process of removing free pyridine and sulfurous acid is increased at the same time, so that the product contains very little free pyridine, SO32-and organic salt content, thus ensuring the purity and stability of the product. It prevents abnormal phenomena such as blackening of plated parts, roughness in high areas, blackening in low areas, and more pinholes. 4. in the high current density region, the leveling property is excellent, the decomposition products are few, and the coating can produce a certain white bright effect. |
use | strong leveling agent for preparing electroplating brightener and nickel plating watt brightener formula for bright nickel plating, it is an efficient bright additive, making the coating good symmetry. Usually it is used with saccharin, acetylene compounds, and wetting agents. The nickel plating layer thus obtained is bright and flat with good ductility. |
