Product Applications
Acid Copper Brightener in Electroplating Industry：
1. Mid-Low Current Density Grain Refiner: Functions as a brightener in mid-current density areas, effectively refines grain structure, resulting in denser deposits with fast brightening and excellent bath stability.
2. Brightness & Ductility: When combined with polyethers, wetting agents, or other sulfur-containing brighteners, produces deposits with good brightness and ductility.
3. Synergistic Effect: Achieves optimal performance when used with SPS at a 1:1 ratio. DPS helps balance SPS, M, N and other additives, while complexing cuprous ions to reduce plating defects.
4. Precious Metal Electroless Plating: Serves as a stabilizer in electroless plating of precious metals to prevent spontaneous deposition.
New Energy Materials：
1. Copper Foil Electrolyte Additive: Used in producing high-quality lithium battery copper foil. Grain refinement improves foil uniformity and mechanical properties.
2. Battery Electrolyte Additive: Enhances electrolyte performance for new energy batteries.
3. Fine Chemical Intermediate: Serves as a raw material for synthesizing other functional compounds.
