Potassium diphenyl sulfone-3-sulfonate

Potassium diphenyl sulfone-3-sulfonate (CAS 63316-43-8), also supplied under the trade name Provichem 0216, is an anionic surfactant used to modify surface energy. It improves wetting and dispersion in aqueous industrial systems.

Its sulfonate functionality delivers strong substrate affinity across a range of polar and semi-polar surfaces. In textile processing, it functions as a wetting and leveling agent during dyeing operations.

This chemical improves dye penetration and uniformity across fiber substrates. Printing ink and coating formulators use it to reduce surface tension and enhance ink spread on treated and untreated substrates.

By improving print definition, it serves as a vital component in high-quality imaging. In paper manufacturing, it supports sizing and surface treatment processes where controlled wetting is critical to coating adhesion.

Leather processing operations incorporate it as a dispersant and penetration aid in tanning and finishing baths. This ensures consistent results across various grades of leather and synthetic materials.

The product is typically supplied as a powder or as an aqueous solution, depending on the supplier and application requirement. Technical grade is the standard commercial offering for industrial surfactant applications.

Packaging is generally available in bags or drums suited to industrial procurement volumes. This ensures safe handling and efficient storage within large-scale manufacturing facilities and chemical warehouses.
