Application:

As brightener in acidic Copper baths and has the effect of depositing a bright and ductile coating when combining with polyethers and wetting agents. A combination with other sulfur-containing brightening additives is also possible. For the chemical deposition of precious metals, DPS is used as a stabilizer to prevent wild deposition.
