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 across construction and industrial processing to control rheology and promote flocculation.

Its sodium salt form delivers water solubility and compatibility with ionic systems, making it a practical choice for formulators working across multiple substrate types and complex systems.

In construction, it functions as a dispersant and rheology modifier in cement and concrete admixtures, improving workability and flow without excess water addition during the mixing process.

Textile and leather processors use it as a leveling or retanning auxiliary, where controlled charge density helps achieve uniform dye penetration and surface treatment for high-quality finishes.

In paper manufacturing, it supports wet-end chemistry as a retention and drainage aid, contributing to fiber flocculation and sheet formation during the industrial production cycle.

Coating and adhesive formulators incorporate it where crosslinking density and film cohesion need to be tuned through polymer network interactions to ensure long-term durability and performance.

This product is typically supplied as an aqueous solution, with solids content varying by grade. Technical-grade material is the standard commercial form for most industrial processing applications.

Buyers should confirm active solids content, pH range, and ionic character when evaluating grades for specific formulation compatibility to ensure the polymer meets all necessary requirements.
