Potassium diphenyl sulfone-3-sulfonate

Potassium diphenyl sulfone-3-sulfonate (CAS 63316-43-8) is an anionic surfactant used to modify surface energy. Also marketed as Provichem 0216.

Where is Potassium diphenyl sulfone-3-sulfonate used?

• Textile processing: wetting and leveling agent during dyeing, improving dye penetration and uniformity across fiber substrates
• Printing inks and coatings: reduces surface tension and enhances ink spread on treated and untreated substrates
• Paper manufacturing: supports sizing and surface treatment where controlled wetting is critical to coating adhesion
• Leather processing: dispersant and penetration aid in tanning and finishing baths
• It improves wetting and dispersion in aqueous industrial systems.

Good to know: Its sulfonate functionality delivers strong substrate affinity across polar and semi-polar surfaces.
