2. Grain refinement is the core functional advantage of SPS and MPS.

 

Grain refinement is SPS & MPS’s core merit. Ordinary acid copper plating generates rough, loose coatings with disordered coarse grains, weakening conductivity, corrosion resistance and mechanical performance. Added to plating solutions, they boost cathodic polarization to regulate copper deposition, restrain large crystal formation and arrange copper atoms evenly. Microscopically, they miniaturize grains and compact deposits for flawless smooth copper films, solving classic plating defects fundamentally.

 

3. SPS is a high-efficiency electroplating intermediate

 

As a classic high-efficiency acid copper intermediate, SPS boasts wide compatibility. For hardware plating, it forms glossy, anti-oxidation copper layers. For PCB & copper electroforming, it produces dense, conductive deposits for precision electronics. In lithium battery copper foil production, its grain refinement boosts surface finish, tensile strength and ductility, enabling stable mass manufacturing of ultra-thin foil with consistent battery conductivity and longer service life.

 

4. MPS delivers complementary core functions to SPS.

 

 

MPS shares the same grain-refining function as SPS and works synergistically with it, compatible with all acid copper plating conditions. Featuring great stability at high temperature and high current density, it avoids burnt, uneven coatings and offers strong throwing power for complex parts & high-speed copper foil lines. Usable alone or blended with SPS to elevate plating effects, it ensures steady quality for copper foil and functional copper plating.

 

5. Industry Development Trends

 

Booming new energy and precision electronics raise stricter standards for copper coating precision, gloss and stability. With reliable grain refining and broad process compatibility, SPS and MPS are essential additives for acid copper plating and lithium battery high-precision copper foil. They enable high-precision, mass high-quality copper plating, supporting hardware, electronics and new energy industrial upgrading.
