Application

SPS is the top brightener for acid copper plating. SPS is used in decorative plating and electronic plating as the top brightener. SPS can be used in combination with polyvinyl alcohols, non-ionic surfactants, amine polymers and other sulfur-containing compounds. It can also be used with a stain. It is used as an acid copper brightener to obtain decorative and functional coatings. It can be used in combination with typical copper plating formulations such as non-ionic surfactants, polyamines and other hydrogen-sulfur compounds, and can also be used with dyes, if combined with DPS and EXP2887, it will get better results.
