Significantly enhances the tensile strength of electrodeposited copper foil.
Functions as a combined grain refiner and leveling agent, resulting in a smooth and fine-grained copper deposit.
Its performance is similar to SPS (Bis-(3-sulfopropyl)-disulfide,Cas No.27206-35-5), but it is uniquely designed as a synergistic product that integrates both grain refinement and leveling properties.
This technology is specifically recommended for PCB copper plating applications.
