Phenolsulfonic acid-formaldehyde-phenol-urea polymer, sodium salt

Phenolsulfonic acid-formaldehyde-phenol-urea polymer, sodium salt (CAS 102980-04-1) is a sulfonated condensation polymer used in construction and industrial processing to control rheology and promote flocculation.

Where is Phenolsulfonic acid-formaldehyde-phenol-urea polymer, sodium salt used?

• Construction: dispersant and rheology modifier in cement and concrete admixtures, improving workability and flow without excess water
• Textile and leather: leveling or retanning auxiliary for uniform dye penetration and surface treatment
• Paper manufacturing: retention and drainage aid supporting fiber flocculation and sheet formation
• Coatings and adhesives: tunes crosslinking density and film cohesion through polymer network interactions

Good to know: Buyers should confirm active solids content, pH range, and ionic character when evaluating grades for formulation compatibility.
