Description

Phenol, Polymer With Formaldehyde, Sulfonated is a synthetic, water-soluble resin derived from the polycondensation and subsequent sulfonation of phenol and formaldehyde. This chemical modification imparts strong anionic character and enhanced dispersing properties, making it a valuable functional additive in numerous industrial processes. It is primarily utilized in sectors such as water treatment, construction, textiles, and oilfield operations where its ability to control scale, disperse particulates, and modify rheology is critical.

Application

• Water Treatment: Acts as a highly effective scale and corrosion inhibitor and dispersant for calcium carbonate, phosphate, and other salts in cooling water, boiler water, and reverse osmosis systems.
• Construction & Concrete: Used as a plasticizer and superplasticizer in concrete admixtures to improve workability, reduce water content, and enhance the dispersion of cement particles.
• Textile & Dyeing: Serves as a dispersing agent for dyes and pigments, ensuring uniform color distribution and preventing agglomeration during the dyeing process.
• Oilfield Chemicals: Employed as a mud thinner and dispersant in drilling fluids to control viscosity and fluid loss, and as a scale inhibitor in production operations.
• Paper & Pulp Industry: Functions as a dispersant for pigments like calcium carbonate and kaolin in paper coating formulations to improve sheet quality and printability.
• Ceramics & Paints: Aids in the dispersion of inorganic fillers and pigments in ceramic slips and paint formulations, improving stability and application properties.
• Industrial Cleaning: Incorporated into detergent and cleaning formulations for its sequestering and soil-suspending capabilities.
