Controlled by the degree of response indicators, while increasing the removal of free pyridine and the sulfite process, thus products containing free pyridine, SO32-, organic salt content is extremely low, to ensure product purity and stability. To prevent the plating black, high-District rough, low-area black, more pinholes and other anomalies. 2) Quality Standards: Q/LZ 05-2008 Appearance: Colorless to yellowish liquid PH Value: 4-5 Density: 34 Baume degrees Solubility: Well soluble in water Dioptre:64 Assay: min 45% Na2SO3: max 0.3% NaCl: 12% PPS-OH salt: max 1% free pyridine: 50PPm 3) Application Concentration in the bath:50-500mg/L Consumptio:40g/KAH Usage: Stronger leveling agent in nickel bath Characteristic: Leveling particularly good in the high current density zone, can produce a certain effect of white light to the coating.
